I installed the Draw-Tite 76138 last weekend, went well. I plan to do the wiring sometime soon, probably going with the Tekonsha no splice kit. But as for the ball mount, Im wondering what most of you folks go with as far as rise on the ball mount? The top of my hitch receiver opening is about 13, actually maybe a smidge under that. I see on Uhauls site, they claim an 18 coupler height for most of their trailers. So that would mean I need a 5 rise. But arent most run-of-the-mill utility trailers in the 16 to 17 height? So Im torn between a 3 vs 5 height. I know... I could go with an adjustable hitch, but not sure I want to go that route. Im leaning toward a 5 rise, since most likely when towing Ill have some weight in the back of the vehicle anyway which will lower the hitch a bit too. Anyway, just curious what the going rate seems to be on hitch rise. Thanks.
