decals peeling and cracking on a 6 year-old camper is not unusual and that's for all manufacturers, not just FR.
i had a front bunk door replaced on my '07 HTT, in 2010. the new decals on it have already lifted, cracked and peeled. since it faces the sun all day and since i don't cover it, the California sun does its work on it.
on a 2008, it's out of warranty but you can order new decals from FR parts dept.
