We have an 86 Holiday Rambler 30 foot we bought in OR in April...is this what you are looking for:
Its a great RV, so well made. If you want more information, please ask. The RV frame is made of aluminum; the lower side panels are fluted (horizontal), top panels are also aluminum as is the roof.
We decided also to keep our Bigfoot camper/f-350 for more remote RVing.
Gosh, I just reread your message...to see that you have an apache popup. We had the same one, bought in Nova Scotia in ~1969 and even towed it with a VW bug; later we bought a 66 TC Rover (sedan, not the landrover)....we eventually donated our apache to the Boys Scouts.
