We use to have a Winnebago Sightseer with the 8.1 GM gas motor and had very little problems in the 68K miles we owned it . Great motor and cheap to maintain. We had to sell it because we started towing a larger enclosed trailer for our business and bought a 03 Safari Sahara DP with the 8.3 Cummins 350 HP. Biggest mistake I've made in my life. Over $40K in repairs in the 80K miles we have put on it. This does not include maintenance. This MH has created a tremendous amount of stress in my life. The interesting thing is I talked to many who are in my business who use their MH for the such. Before I bought this DP everyone said how great they are, after owning this thing and telling them the problems I had been having they then started telling me all of the problems their having. It seems misery loves company.
This DP is essentially now traded in. It actually doesn't happen until our toy hauler is built and delivered which I hope happens in the next few weeks. I can't get rid of this thing fast enough.
So here's my advice to you; whatever you buy make sure you get an extended warranty, it saved me a ton of money.
I know many people who own the 8.1 GM and the V-10 Ford gas motors. Some of these people have in excess of 150K miles and one fellow with the Ford has over 220K miles. All of these have for the most part been trouble free low maintenance miles. They get about 7 MPG at $3.57 a gallon. I get 9.5 MPG at $4.22. You do the math. Changing oil in my DP 5 1/2 gallons and a almost $50.00 oil filter. 8.1 GM 7 1/2 quarts and a $5.00 filter. Air Filter DP $175.00, 8.1 $15.00. It goes on and on like that and as I mentioned repairs that aren't maintenance are extreme.
Since you have already been camping and are thinking full time, have you ever notice why so many full timers are using a fifth wheel? You really should give that some serious thought.
Before we were going to buy this DP another person I know who use to be a diesel mechanic and worked on many DP's warned me not to do it. I should have listened. Personally I may never own a MH again, I'm going with the toy hauler. Good luck in your decision and happy trails.
