When I bought my Pleasureway Traverse (also built on the Ford chassis) it took me a while to figure out how to swivel the seat. Before you start make sure the recline has been moved to the most upright position possible (straight vertical). Once this is done the key is that you need to pull the swivel release, turn it a little way toward the center (counterclockwise if you are looking down from the top), then pull the forward-back release and shimmy it back and forth while turning the seat. No one position will get it to turn, but by changing it as you turn it will eventually squeeze around past the engine doghouse.
I don't have a Pleasure Way van, but in my class B both seats turn toward the center of the van, and they each have to be slid forward and back to get them completely turned around so they face the back of the van.
