I've had our 2011 Crossroads Zinger for close to three year now. When I first got it I went through everything and cleaned out the old caulking on all of the joints, and redid it. Then last summer I noticed that some of that caulking had started to crack and look pretty bad so I redid a bunch of it again.
And now this summer/fall I've started to notice that once again, I can see several spots were the caulking around things has started to pull away and/or crack...and needs to be redone.
I've always used the high quality (and expensive) RV caulk, and it just doesn't seem to last very long.
Is that pretty normal, or am I doing it wrong??
If you're specifically talking about self leveling lap sealant here is a story for you that brought back memories from a 2011 Aerolite we had which was built in 2010. Back around that time (2009/2010) Dicor had sent a bad batch of lap sealant to multiple manufacturers, and since your 2011 could of been built as early as late fall of 09, perhaps your rig received a dose of it. On our 2011 Aerolite all the roof lap sealant dried out and started cracking at about 1 year past the build date. I traded it in not long after and the dealer knew about it. I assume he took care of it before re selling, and was reimbursed by Dutchmen/Dicor.
I have not had one prior, or of the two since, where the lap sealant cracked like it did on that 2011.
