Well, my $0.02. Last year we were in somewhat similar situation. Want a class A, have 60-70K to spend, what is the best for our first class A?
Diesels are the cream of the crop, but have higher cost of ownership over the long term. Gassers are less expensive to buy, and easier to maintain but a bit less comfortable (though we are quite comfortable in ours).
We have ended up full timing though we were not sure we would.
After extensive research we ended up with a Winnebago Vista 2015 31' from a private seller who ate a significant amount of depreciation. It had 7,400 miles on it so it was like new. A bit of oxidation on the exterior but still looks nice.
What I would do differently if I did it today:
1. If you buy a gasser, get a 2016 Ford F53 chassis. Its a 6 speed and that is a difference maker (mine is 5 speed).
2. Go longer than you think. The 30' length is a bit short and you will not have room for what you want and the chassis GVW is too light. Go longer you can safely carry more (more weight capacity). I would go at least 34'. After a couple days driving you will not notice the difference.
3. Look for the biggest shower you can get! (a personal bias).
4. If you have space you can put a portable washing machine and use bathroom water and shower drain to do your own washing.
5. Put sway bars and sumo springs on a gasser, diesel will have good suspension. (about $2,500)
6. I got a single slide model as I have slide-a-phobia and worry they will not work. Simple is better and I dont advise kitchens that slide out, more to worry about and repair in the future.
Start saving for your next coach... after you have lived this for a while.. you will start thinking of what you will want, however, you may find you have a good rig and find ways to 'adjust' it to what you want.
FWIW.... Turn the key and smile!
