On my 2000 Marquis my 2 slides have a small amount of sag in the corners, 1/4 inch at most. On my main slide the rollers began to wear into the bottom of the wood floor. I installed 5 stainless steel sheets 10" X 16" so the rollers would rest on the metal plates during transport and reduce the continued wear to the bottom of the floor. Well the heaviest portion of the slide continues to imprint on 2 stainless plates because I installed 26 gage if I remember, was not heavy enough material.
The reason I am posting is because I have read that some have used Delrin Sheets and am wondering how that will hold up to the roller wear and continued contact during transport. I will need 1/8" and 3/16" thick sheets to regain the original ride height and match the paint lines on the coach exterior. Any impute on the Delrin product would be helpful.
