One of our friends bought a new 2004 Trail Lite 235S after seeing ours. I had a chance to see it this weekend. Some great improvements:
Out side storage compartment is larger by the addition of a pan that extends it from the floor line downward. This looks like it required the movement farther aft of the battery tray making it more accessible.
The nose of the roof shell is more bulbous, coming out over the windshield. This allowed the TV and front cabinets to move forward and permitted a larger cut out where the driver and passenger get up to go back into the coach. That change also added a cabinet on either side (over the driver and over the passenger.
There is a heat outlet in the bathroom now but the main heater outlet looks like it was eliminated for 3 round outlets (under the dinette, in the bathroom and on the curbside wall.
The refrig is now a two door version with a freezer up and refrig down.
A spare is mounted on the back wall on the driver side. It looks like they added drag bars (exactly like I had made).
Sounds like R-Vision is actually listening to customers,
Two things I didn't like are no fantastic fan in the aisle and they separated the oven and microwave. The mic is now above the range and the oven below, effectively eliminating the cabinet over the range.
