Moto trailer build

Backstory:

When I moved out of the Bay Area a couple years ago I bought a huge cargo trailer to move my stuff with the idea I would re-sell it in Oregon, my new home. I did just that (the loss on the re-sale was still considerably less than the U-Haul scenario) but while I owned that trailer I realized how handy they can be. Since I enjoy coming back to ride and visit but don't want to ride the 500 miles on my Hypermotard, I purchased another cargo trailer that was an appropriate size for the need. I ended up with a 6'x12' Interstate Pro Series with extra height so I can stand up inside without ducking my head. The big reason for the Pro Series over others was the torsion axle. After towing the trailer around I could not be happier with my purchase.



Build:

The first thing I did was take out all the e-track so I could paint everything. The floor is a marine deck non-skid and I used marine enamel on the walls. I was really excited to hit the road and give the whole thing a test run. As you can see my setup was pretty spartan with a cot, folding chair and a couple cheapo battery powered magnetic led lights. Basic as it was, it sure made life more comfortable than sleeping on the ground like I did with my old RC!

As nice an upgrade as the trailer was, it needed something to make things more comfortable.

First thing was to have the dealer install a window. I could have done it myself, but the cost was reasonable and they did a really nice job in an afternoon. Money well spent.

The second item was a heater, and from there things snowballed. I decided to build some cabinetry in the front so I had a counter, place to hang my leathers, etc. One of the drawbacks to these trailers is the lack of any real electrical system. When I am plugged into the truck with the ignition on the lights all worked, but when the ignition was off, nothing. Like most people I thought I would just add a battery and let the truck charge it while I was driving. As many of you probably know, that idea was a pipe dream without adding a battery to battery charging system in my truck and running heavy gauge wire to the rear bumper. When I factored in cost and practicality it didn't make sense for my needs. I settled on solar with a converter to charge the batteries and run my 12 volt system when I was plugged into shore power since I stop at RV parks here and there for a shower and civilization.

Moto trailer build - 2

Why add heat if you aren't going to insulate? Now things started to get interesting. I also added a roof vent/fan, ordered a Dometic portable fridge and got to work designing an electrical system. I designed my solar rack to tilt either left side or right side of the trailer to take advantage of low angle winter sun. The component selection consists of Renogy 100 watt solar panels (x2) Bogart Engineering solar controller and battery monitor, Trojan 6 volt golf cart batteries wired in series, a Progressive Dynamics converter, AC breaker box, shore power inlet and an exterior GFCI, interior AFCI (only available while plugged into shore power), a Camco Wave 3 heater, and an aluminum tongue box to mount propane tanks to and install the majority of the electrical.

The AC breaker box (main lug, backfed) converter and 12 volt fuse panel ended up inside.

Moto trailer build - 3

The remaining pictures get me to where I am today. I am waiting on some wire and connectors and need to finish the ceiling. Hopefully I finish just in time for the smoke to clear from the Bay so I can come ride. I will post up the rest of the pictures when I finish in a couple of days.

Some other details:

My kitchen is an outdoor camping type with a table, stove, and all the rest that lives in the bed of my truck. The second propane tank on the tongue box is for the stove.

I used all marine grade, tinned wire and heat shrink crimp connectors (Ancor), FTZ power lugs and crimper for the battery cables and everything bigger than 8 AWG. 2/0 welding cables for the battery cables and big wire through the build to minimize voltage drop.

I am also trimming out all the gaps in the walls with hemlock. The ceiling and hemlock trim are mounted by drilling and tapping the steel frame with stainless hardware and finishing washers. The trim from the factory is just strips of door skin stapled to the plywood. I didn't want to have to repaint every time I took down a wall panel (hopefully never!) so that was why I decided on screwing the trim down.

The bed is designed to fold up to the walls so I still have full use of the trailer for hauling. The wider bed is for me and the Moto, the narrower side acts like a bench/couch and with both down there is a third piece that fills the gap making it a queen size platform. I also moved the spare tire to the exterior for more room inside. Eventually I am adding an awning.

I’ve got a 6x12 trailer also and been considering doing enclosed trailer conversion thing also. I was considering a roof top ac unit and a quiet Honda generator along what you have already done.

I’ve been toying with the concept of base site touring. The concept is finding a base site somewhere that is central to some interesting looking roads and places and do day rides out and back for a few days....a week and then pack up everything and move to the next base site. Most base sites will be campground based.

Base site touring has been my program since I picked up the trailer. In May I camped off Hwy 9 at one of the RV parks, at HMB, Guerneville, Garberville and Crescent City. I rode 1600 miles in 7 days on that trip (turned 50 years old and had to commemorate). More fun for me to camp and ride amazing roads than wearing out tires and trying to live out of a 20 liter Kriega bag for a week! With the solar and kitchen setup I am hoping to do more boon docking and free camping.

I estimated ~35Ah of daily consumption and should be able to match or exceed that with my solar charging. Even if it doesn't get me to a full SOC, with 225Ah batteries I should be able to go 3-5 days without issue. An overnight at an RV park plugged in or plugged in back home would bring me back to full charge. That is the dream, anyway.

Wow, nice. I just got one and need to build some cabinets and run a little wiring. Hopefully I don't get that crazy :laughing

Awesome, thanks for the pics. When I first got my 6x12 I was envisioning something very much like your build.
But I am both lazy and without skill, so pretty much all I ended up doing was screwing Gladiator brand garage organizers to the walls so I would have a place to hang/store stuff...

I do have one tip for you; ditch that wheel chock and install Pit Bull Trailer Restraint(s). They are expensive but 100% worth it.

Yeah, I just can’t see wasting my Tracer doing highway miles to get to the good roads. Plus, I got a couple of telescopes for star gazing....be nice to have at night for something to do.

There are some roads on the east coast I want to do and places to see. There really is a lot to see in this country.

Where you getting a side awning?

If I own this trailer for the rest of my life it will make sense financially ;)

There are cheaper and easier ways to go about all of this, but I found that hotels and restaurants add up quite a bit while touring around. I have tools and currently time, but a lack of either would make this project very difficult. There were a few tools I picked up to facilitate the build that would push the economic viability of the project past most reasonable limits. Unfortunately there aren't many ready made options that suited my needs and if they did they far exceeded my budget.

Thanks for the nice comments, and feel free to ask questions.

I have my eye on a Thule Hideaway. It will work well for this trailer, but it is a grand. That will have to wait for now.

I looked into the Pit Bull restraint and they are very cool. I wasn't that excited about having the mount in the floor and already owned the Baxley chock which works great. In retrospect the Pit Bull would be the way to go if didn't already have the Baxley and Canyon Dancers.

You already installed a whole bunch of other stuff in the trailer, why would you be worried about bolting a plate to the floor?

I also have a Baxley and Canyon Dancers. I still use them for transport in truck beds.

The best thing about the Pit Bull TRS (other than the fact that your bike will never fall over) is simply not having the chock and straps in the way inside the trailer.
It's one of those things that's hard to bite the bullet, because they are expensive, you have to install them, and a chock/straps works just fine. But once you go for it you will see the light and kick yourself for not getting them sooner. I did.

Currently I am kicking myself for dumping so much money into this trailer.......

Just a suggestion.........and you may have already......put a tire pressure monitor system on the trailer. I had a trailer tire go down last year and never felt it and only knew about when a car passing pointed it out.

I’ve been considering doing this for windows....

Plus one in the side door and rear doors.......I have swing open rear doors. I figure the more windows, the less enclosed it will feel.

I’ve been planning my base site country touring trip for a long time. I had to get my tow vehicle in shape,which is done, I had to find the right bike cause the 94 Seca II wasn’t gonna suit my needs,which is done, and now, the trailer needs the proper attention to make it comfy.

So, those doing or planning to do a conversion, post ideas and parts list.....
