I have the 95 30ft Fleetwood Prowler which looks to be the same RV.
Were you able to push the slide out the last bit by hand or did you need a come along or jack of some kind? Did the slide floor rollers give you any trouble going in or out?
What slide mechanism does yours have and what kind of seal did you use on the bottom of the slide when you put it back, or were you able to salvage your gasket on the bottom? Mine uses a cable system and I unwittingly destroyed my gasket/seal when I removed the carpet several years ago. I used a machete to break loose the carpet under the slide and got to rambunctious :(
Likes like you did a good job, is that a 2 x 6 you replaced the rotten beam with?
