I have a 30ft Class C E450 and have 2 racks. One is the lift rack with hydraulic (pump) lift, the other has a ramp to get on carry rack. Neither effect handling at all. The Hydraulic rack raises the bike pretty high.....to high for use on my front 2" hitch...it I want to see where I'm going! So the ramp one in the front, Hydraulic in rear unless I'm pulling a trailer.
