Thinking about Auxiliary Trailer Build

My business needs led me to purchase a 12ft cargo trailer from a guy who initially had it converted as a small home-made camper. He had removed most of the camping stuff but I'm left with two windows, a power vent in the roof and insulated walls.

My initial thought was to build out the camper and use it just for my business by having it as a sort of mobile show room for my product. I then got to thinking that maybe I could kill two birds with one stone. The camper is great for the fiancee and myself but our two girls (10 and 8) can make it a tight squeeze. When we go camping with my parents they just use tents at the campsite but I feel guilty being in a nice toasty camper while they are roughing it out in the cold.

What I'm thinking now is to just hang my product on the back doors of the camper (perfect because I can swing the doors open and everything is right there to be seen) and then build in some fold out bunk beds that will store flat against the wall of the camper (so I can haul my Honda Odyssey). Up front I'm thinking about building a small room just big enough to hide a porta-john (save's the girls from knocking on our door in the middle of the night) along with some upper and lower cabinets along with a counter and small sink.

What I listed above seems to be fairly easy to do and will be a fun build however I am now wondering what else can I add? I've thought of the following so far...

1. Additional Solar Panels + Battery Bank
2. Roof Rack for Kayaks or small Sail Boat
3. Additional holding tank for grey / black water
4. Large capacity freshwater tank
5. Large awning / sun room system
6. Outdoor portable kitchen setup

The auxiliary tanks would only be for transferring between the camper when stationary an obviously not hooked up while driving.

Given the list above, this should keep me pretty busy (and broke) till summer time comes around. Does anyone else have any other suggestions to consider incorporating into the trailer? Any other examples that could be referenced? Pictures?

    Wow. That's a lot in a 12' trailer.

    Single axle, or two? Weight rating? Only asking since I have an extra wide 12' pipe rail utility trailer with a single 3,500 lb axle. But sticker on the frame says not to load over 1,870 lbs.


    Double axle trailer. I'll have to check and see what the load capacity is on it. Batteries and extra holding tanks does tend to add up fast.

    With solar, if you put a couple extra batteries in, you can run a decent sized inverter. I have 600w solar on mine, with 3 120Ah batteries going thru a Xantrex 1.8KW Prosine inverter.
    The solar has no problem keeping up with the 110v LED lighting(when used) and full size 18cu ft fridge over a day/night cycle. I usually have enough let over to also run a self-standing ice maker that draws 400 watts.


    Extra fridge and ice maker... I like that idea! What type of fridge did you use?

  • I've been doing some research on google and YouTube but I found everything to be built as a standalone trailer application and not as a secondary support to the camper when needed. Things like transferring fluids between the two and battery / solar setups is where I need to do my homework on and was hoping others here might have tackled a similar project.
  • I think you have most of it, but I suggest looking at youtube videos for trailer toy haulers for more ideas.
