Update:
This past week we finished up the belly (1/16" aluminum Sikaflex 252 glued to the steel base frame) and some of the walls. Progress still slow because of the fickle nature of the Sika 210 primer (once you open it you have about 20 to 30 hours to use it or $50 is down the drain).
One pic shows the siding pieces with cutouts for the jackstand quick-connect mount and the water heater hole. Another pic shows the finished belly, all nice and shiny aluminum...probably will coat that with something, but the Rhino guy says he can't get his equipment under a camper. The last pic shows us using every rare earth magnet to put the final piece on the back wall...magnets were the only way to clamp it in place while the Sikaflex 252 sets. Could have used about 10 more magnets so we could do other stuff while this one dried.
We are thinking now of going with spray in foam, done by a contractor, instead of cutting out the pink or blue stuff and fitting it in ourselves. I need to research this to find out what type to use and what to do about fire protection and smoke protection from the foam.
