I agree that something else is going on with the first one.
For 4 weeks a year, if that's all you'll really use it for a gas MH is good. If more than that such as a weekend here and there, holiday weekends etc. I think you should stick with a gas Motor Home. Maybe even look at class C's some of those have bunks too. A DP (Diesel Pusher) would be better suited to longer more often trips. Does the DP you are considering have a slide out? I can tell you that with kids a slide out is a must. Nothing wrong with a DP if you're going to excersize it frequently on some long trips.
It's hard to say what is best because I don't know your traveling style i.e. close to home trips less than 50 miles or long trips of 500 miles or more!
