I paid a LQ conversion guy to build my conversion.
Iowa Cowgirl,
All is not lost! Horse trailers with living quarters will outlast virtually any RV with the possible exception of an Airstream. The horse trailer is made with axles that are up to the job, tires with weight ratings that are realistic, no filon sidewall delamination possible, no rubber cheap roof that only lasts 12 years, etc. In the long run you have a superior RV that in the short run needs a few minor things fixed inside. That is way better than a new standard white box that will need lots of things fixed on the outside as it ages and that came with barely able axles and tires. Keep your chin up and I am sure the electrical issues will be solved to your satisfaction very soon.
If I was looking for a toyhauler that would go the distance, I certainly would have on my short list a living quarters horse trailer.
