I guess this post is getting revived. I will be doing some aluminum sheet metal work on one of my old coaches I acquired back recently. So, I will be finding out what gauge the metal is and post the info.
I will be continuing to do whatever upgrades needed to this 1978 38' coach, until hopefully a buyer come's along to take it off my hands. It would be a great deal for the person wanting to do their own upgrading. I'm also saving up for a little newer larger Newell to full-time in. Ken
