Thank you so much. This is exactly what I wanted know.
It is a bit of a handicap never having seen another Ventura
. And they certainly are not showing up on youtube, unlike Bolers and Shastas .
This trailer has a very noticeable slope and I want to eliminate at least some of it, if possible. Perhaps force was too harsh a word, more like coax.
Whichever, the floor at the door does need some reinforcing.
I had been wondering about the gap between the bottom of the frame and the fiberglass. It seemed about the depth of the plywood on the floor.
I took the door and frame (along with the windows) off today so now know what I am dealing with.
We are in for a stretch of rain so I have something that I can work on in the garage until I can get back to the trailer.
Again, thanks for all your help.
