In many cases, I was able to manage solo (I’m a big guy and used to working solo) — however, there was higher risk of a problem (damage to the camper, a tool or me). I assessed the risk and tested the process before committing to doing it solo. I did get a helper for a few short steps such as when I had to flip the assembled camper over, but I was able to do all of the other steps solo.
I plan to get the Trailex trailer in the spring when I finish the camper off. I did look at some other trailers, but figure if I’m putting all this work into the camper, why not go for the deluxe trailer… I’m sure that others will work, but one that I found (and aluminum trailer from Northern Tool) looked good but after looking at reviews I found that it was only rated for 55 mph… I would rather spend the money for a trailer that I know will work and is light weight. I’ll be putzing with my camper a little over the winter, but mine is essentially all assembled and coated with epoxy. I have to cut a few holes for vents and electronics when I purchase those. I’m kind of on hold until I save up the money to buy the second wave of stuff. I’ll be storing my unit in my shop for the winter.
I just discovered this forum a few days ago… I wish I would have had it available and known of it when I was in my building phase. I see a lot of good information here and it is inspirational to see what others have done or are doing. This is a great project! Just read the instructions carefully and poke away at it. If you have more time when you’re working on it, there are steps that can be done in parallel (versus performing the steps in the order they are written). When I had more time on some days, I would look ahead in the instructions and find things to do that didn’t depend on the thing that I had just finished. This helped me accelerate my progress.
Good luck to you and enjoy your project!
