I went through a couple challenges with the TLC system but it turns out, 1/2 the problems were mine. 2 of my "leaks" were me not pushing the tubing into the bags far enough. Sounds stupid but it was real. Another was me not pushing the tube into the schrader valve far enough.

I will say that if you give John and crew a chance, they'll make it right.

I pull a 31 foot travel trailer and put 2 motorcycles in the back of the truck and the bags make all the difference in the world. But I'm also using about 1200 dollars worth of anti-sway/WD hitch system which makes a huge difference. Might also wanna think about LT tires to stiffen up tire flex / sway.
