72"x144" 5052-5086-6061 aluminum sheets. Been searching the net and cannot find any local suppliers offering anything wider than 48". I'm redoing the floor in a 21 ft 73 Starcraft Mariner which previously had plywood. I'm re-bracing it port-starboard with 1 1/2" x 1" channel every 10" across the top of the existing ribs.

I got 6' x 20' in stock. Though, freight would be a killer !!!

Thanks J, like ya said shipping will be a pain. I may have found some closer, if I can convince them to sell direct.

how far are you from Pioneer Ohio? If you want to make the drive i can get them that far for you. i have a truck that goes that direction every week that arrives Sunday night aroudn 10pm. Ill get a price.
