Have had our 19' for almost two weeks now and naturally, I'm wondering what I can do to "enhance" it just a little. I'm of course thinking basic stuff - where can I attach this or that, where is there a 'stud' I can tap into, and how far can I drive a screw without rupturing a water line (or heaven forbid, a tank). Anyone out there ever compiled a listing of where the structural framing is and where a screw might find some thing to sink its teeth into? Is there a plywood subfloor under all the linoleum (and if so, how thick is it)? Can I use my framing nailer?
