Hahaha! Beer can meassuring cup that's funny 'cause I've done it, to meassure pancake mix.
Well in the last 4 days we've towed our new 29L 2000 miles and I'm impressed, it tows great and I didn't get the sway control cams for my Reese WDH. This is my first time towing with a WDH and I can say I'll never go with out again, huge difference in the way bumps are transfered to the TV.
We do have a slight leak in one window but tha was also while towing through a thunder storm that was aproaching hurricane status. It was raining sideways with 80mph winds.
