I’m officially offloading my RSI cap and RTT and going hardsided! Question is should I build the cap myself out of wood or convert an S250G comm shelter? Deal is I want to be able to sleep east west, have a bunk for my kid, and it all has to fit on my 6.5 ft truck bed (2015 Ford F-150 v8 5.0l super crew w/6.5 ft bed) thoughts? Thanks ahead of time!
