Going into the 4th year of use on my XP18CC (mod-v hull) and haven't had any issues with it so far. Which is a good thing because it almost caused a divorce when I drove up to the house with it. It has been punished a bit but not abused. Has the scratches to prove it, even one decent little gouge, but I bought a tin boat so i wouldn't have to worry about gel coat on a glass rig. Looking forward to several more years of reliability out of it.
I've gotten caught out in it a few times where I had to battle 2-4' rollers about 10-15' apart. It wasn't pleasant, not even a marginal ride, those conditions beat the snot out of that hull, even taking it very easy. I imagine the hyperlift hulls do a lot better in rough conditions.
All in all, the only difference in choice I might have made, knowing what I know now, is either get the 1872 hyperlift hull, or the 2070 XP/Mod-v hull. Either would have pushed my budget a bit more than I wanted at the time. Just a tad more room around the console would be a good thing. Other than that I am happy with mine.
