I drove the Jeep with my "other" BF trailer up to Henderson, CO, this morning (150-miles or so) to ALRECO Aluminum (303) 287-7210 and WOW! Do they have aluminum...solid round stock up to 8-inches in diameter, box, T, I-beam, sheet, angle, the works!
I bought 3each 4 x 8-ft 0.04, and 1each 4 x 10-foot 0.04, plus 96-feet of 1/2 x 1/2 angle...all for $225. They even rolled it up and loaded it for me!
Worth the trip...I never saw so much aluminum at one time before, and I always go to the big fly-in at Oshkosh where there is LOTS of 'flying' aluminum.
The Cubby looks good to go for early spring try out.
