Stretched benroy

Ok. Frame build will start as soon as I get paid next. But planning the beast has begun in earnest. One question I have, is where can I get 5 foot wide metal for the top? We are plannaing a woodie/metal hybrid, hoping for a single sheet if metal across the top to assist ini waterproofing
Any suggestions on stretching a benroy? Ading. To both length and width...
My inlaws, who drove a class A are telling us that we are crazy...that tells me were on the right path
