Hi Jon,
I've had the Showdown since it first came out. In general, I find it to work fine for me, not a problem that it does not have the gas assist. However, some female friends of smaller stature seem to have problems when they tried it and likely would not go this route. I would suggest that you try the rack on a vehicle that has a similar height to the one you use and have a boat to load as well, I have a Subaru Outback. I did make a couple of modifications, adding some additional padding to the cradles and support bars, what came with the rack was not adequate in my opinion. If you are ever on a paddle with me, you are welcome to try it and see what you think.
Hope this was of some help.
Bob
