blaze, welcome to iRV2.com. We are glad to have you join us here and we look forward to helping you in your quest. I believe this is a wood frame constructed unit. A much stronger unit would be aluminum frame design. Take your time and do like you have begun; research and ask questions. Good luck and enjoy the forums.
