Well since I am just in planning stages here, I have been looking at a lot of campers, trailers, etc. and trying to figure out what will work best for me, the GF, and 2 dogs. One option I am entertaining now is converting a 6x12 cargo trailer into a travel trailer.
We spent a solid few hours looking at all the different offerings we could in the 12-20 FT commercial travel trailer realm and what we found is we liked a lot of them in the 16' range since you actually get a little kitchen space inside. The teardrop config. with the kitchen at the back outside is a no for us. We also want a queen size bed space that converts to a couch, and a space for the dogs to lay on the floor / in their own dog beds and not in the bed with us.
Looking at all the offerings, everything seemed to be a tradeoff. We would find something we liked from an amenity standpoint but not like the layout, or we would find one where we liked the layout but it had stuff we didn't want / need. We would occasionally find something we mostly liked but then it would have terrible finishes, or we would look at reviews and they would have lots of QC issues.
So, I am an architect by trade and generally handy with mechanical components, vehicles, and construction. I also don't hesitate to take my time, do and redo things, and buy quality materials and tools to complete a job well. I figure, why couldn't we just build what we want?
So a couple hours later I drafted up a preliminary plan to convert a 6x12 cargo trailer into a travel trailer. More refinement and ideas to come, but I would love to get peoples thoughts on this that have more experience than I do. 6x12 is probably the minimum size, I looked at 6x10 as a layout, but it didn't leave any space for the dogs. I also know that the quality of these cargo trailers in general is not great, so I fully understand I will be upgrading and bulletproofing it before even being able to start the fun part of the build. I am also hoping to find one with the conventional swing doors at the back instead of the ramp, because I want to retain that function to be able to open it in good weather and hang out on the couch and enjoy the views.
P.S. I am already noticing the rotating table and sink locations won't work together, so I will be changing that for sure. The idea as well with the table is it would rotate so one spot at the couch has a space to work on a laptop or whatever, and alternatively when in bed mode it can be aligned to the base of the bed to watch a movie or similar. Also in that configuration it can be extra prep space for the kitchen. Finally I would want to be able to remove the top completely if it needs to be totally out of the way.
