I need your help in deciding which RV I should buy. The Fleetwood Bounder 35E (2003-2006, or the National RV Sea View, Sea Breeze, Dolphin LX and Tropical (2003-2006). I have not found a floorplan like the Fleetwood 35E. Any help will be greatly appreciated. I currently drive a 1990 Fleetwood Mallard (28'). I would like to move up to a 35"-37" rig. Everyone is telling if I'm going to move up, I should by a Diesel vs Gas MH. I'm set to retire in 5 years and want something that is going to last. Thanks, Guy from San Diego....
