Hi, Bob & welcome! I'm fairly new here myself, but wanted to "chip in" on '96 Serengeti. I bought a '96 Monaco Windsor 36' and it has the propane gen. I have not had any problems with it, but would rather had the diesel gen. I don't have any slides on mine and that would really make a difference when considering "full time" RV'ing. I spent Dec. in Portland in '03 and didn't have any problem with the weather, but there are a lot of "colder" places. Good luck with making your choice. I don't regret mine.
