we have an 04- 25' Safari & while at this time we have no ridge appearing, it is something for which I'll be taking the unit back to JC to check out. We have a VERY
noticeable soft spot in the front of the counter & extending across to the fridge. I'm not for sure but I thought at some previous time someone else on the forum was asking about the very same thing on a new unit. I think JC may have forgotten ( along with many other things ) to add a bracket in this area. Might as well address this issuse up front & while it's under warranty.
Best,
