RV Armor (Lifetime transferable warranty)

We have looked into both Flex armor & rv armor. Rv flex Armor would cost about $6500 at Mesa, az. I believe they require yearly checks at the facility. RV Armor would be about $4000 and I don't remember annual checks. We have a 33' fiver with 3 slides. RV Armor will not warranty the slides because of the potential for tree debris snagging when pulling in the slides, but we clear our slides before retracting. These prices compare to having a new EDPM roof installed by the manufacturer at the former plant for $4000 (+cost to go to Kansas). Although we think the Fl option looks very good, the need to be without our unit for days & transit for rechecks, as well as initial cost difference, is making us lean toward the"driveway" version. We look forward to hearing back from folks who cose one or the other... Thanks!
