We are looking at a 1990 Newell with an 8v92 and a 6 sp (I think) 135k miles. What issues should we be aware of? Has minimal water damage above entry door, crack in wall rear side of dinette. Some other minor things need attention, but nothing major. Also anyone know approx. hitch capacity of the coach? Kind of flying blind on this one. Has a combo diesel/propane water heat but I can't tell if it involves the ebgine coolant or not, but seems to work fine. Could use some help as to what to look for, Thanks in advance, Mark
