6 X 12 would be a perfect size for my NEXT TRAILER. Agh... I started a 5 X 10 and it has taken, working very part time on it, 1.5 years to do what you and your other half did in three days' time in your build vid. Hahaha... how nice to have a helper and some shop shelter rather than one's driveway to work on yer rig. But I'm not too envious... I like what I'm building but it's far smaller, albeit more easily towed w/ my 1/2-ton, same ground clearance, etc... I'll have a report up in the next six months LOL. Congrats! on a great, big, simple, wonderful build! my friend. Safe travels to you both.
