That's very interesting to read about you selling your SMB for this set up. I started out doing the trailer thing, Tenttrax, AT Chaser and finally a Kimberly Kamper, but sold them because I got tired of towing trailers off road. I decided to upgrade to a FWC with a diesel and after using it, I'm really pleased with it, but kept thinking a SMB might be better. The walk through was the most attractive feature.
I dig your build.
