Hi All, I'm a new member and am interested in a used Class C motorhome. I'm 58 and plan to do a significant amount of touring (fishing, sightseeing, sometimes working)over the next few years. I've had a cabover camper for my '06 Chev diesel for years, but need the extra room for wifey, thus the interest in Class C. I've read the threads about gas vs. diesel and have not yet made up my mind. I love my diesel pickup, but it seems to me that older Class C diesels are fairly scarce, and so, reflected in the price. Whatever I buy will likely be 4-10 years old. My question is this- I love winter camping and would like to know what Class C motorhomes are considered '4 season '? If it's simply a matter of adding insulation or heat trace cable, I'd like to know that also. Thanks in advance for your help. Dedgrass Somewhere in the USA!!
