Got a 1998 Coachmen Clipper 1270 and the rear wall had some rot damage. I started to disassemble the rear wall frame and saw that the wood used was 1" x 1 1/2" actual size. I picked up some 1"x2" but of course that was nominal so the wall I'm building is a 1/4 thinner. I'm debating on trying to find actual 1" x 1 1/2" actual size wood, or just take the 3/4" frame I have and attach some 3/8" plywood to it to build up the missing .250" and also add strength? What are some input you guys can offer? I'm a machinist but when it comes to wood......it's a whole different animal to me. Thanks!
