Thanks for the inputs - I'm leaning towards the Retrax as well for the reasons most of you outlined. I like the stop anywhere concept, and I like the ability to see over it. I have a standard 8ft bed, so losing a bit to the canister isn't awful hopefully. I know getting out isn't a big deal, and I do have to get out usually at least once to adjust the height of the trailer as I'm getting close to the pin (I hook up almost every time on uneven ground), but I always hook up alone and I really want to be able to see as I come back. Even when I have a helper, they aren't terribly reliable lol!
Thanks again!
