I don't think you'd have any troubles with the ramp and FWD. In general 2wd will always have less maintenance than 4wd vehicles. If you do go AWD, check an Oasis report before you buy to make sure it hasn't had any PTU/axle seal leaks. If it has, do NOT buy. I know most have been repaired, but I would just find one that hasn't had the problem. FWD you don't have to worry. I can't imagine you having any problems with a jet ski on a ramp unless it was a dirt ramp, or very slimy from algea where traction would be a problem, power sure won't be. I will say the AWD is awesome in the snow and ice, but it sounds like you don't have that worry, so if it was me, with $4 a gallon gas, I'd go FWD all the way - not to mention you should be able to buy it cheaper.
