Did you get a sheet in with your paperwork on delivery which lists all the componenets and serial numbers of the equipment installed on your camper? The slide topper should be listed there.
There's no tag/label on the existing topper or mounting hardware?
Completely unroll the slide awning. There "should be" a tag mounted on the housing for the springs, etc. with information on it. From experience: Getting into a position to read this information--well, , ,
Tough Tops in Yuma Arizona make a great slide topper. It is a heavier fabric then the fabric supplied from the original manufacturer. I helped a fellow RVer replace 3 on a MH last year. It took about 1 hr. / slide and we had our 6 pack afterwards.
