Ok, so here's the scoop. the wife and I are looking to get a used pop up. her requirement is ac... fair enough. So, in my difficult search I found 2 units that I like. 1998 Coleman Sea Pine (NO AC w/ AWNING) 1997 Jayco Eagle 12UDK (W AC & Awning). the problem is that with the Sea Pine I'll have to pay to have A/C put on... not a big deal so long as the dealer can get the price in my range. the problem with the Jayco is only that the private owners haven't ever used the water system, so they claim to not know if it works.... So what do i do?
