Are you talking about irv2 or some other web site? I have done some upgrades on my old 03 Newmar
if your interested, there down in the Newmar forum. Its fun whether its an older coach or fairly new one.
If you go to "FIND" just above you leave the check mark in box and type in what your looking for their have been alot of people that have posted some pretty good upgrades to MH's and TT's that may get your interest.
