They've been installed for about 2 weeks but haven't been towed yet and will update as soon as I do. Installation is quite simple and a lot easier if you have someone to help you. A T-piece was used to connect the hoses together rather than filling the bags individually. The only complaint is that the instructions say to install a 90 degree compression hose fitting "hand tighten plus 1/2 turn, do not overtighten". I twisted my hand plus two turns and they leaked horribly. Went back and tightened them up as best I could with an open end wrench and they haven't leaked since. I recommend for the price, quality and ease of installation. Will update this review once I tow in a few weeks.
