Having come from a similar style of camping as you, I'll chime in on my limited experience with ours.
On the one hand we love it. I have a lot of pride when I see another MBS motorhome roll down the highway. I think they look good.
I had a great deal of concern about propane consumption and the generator but I've not found anything to complain about. We get about 9 gallons or so of propane - I think the generator burns less than 1/2 gallon per hour under load or so.
Mathematically that's 18 hours, but that's ALOT of generator run time for such a small rig. Install a fantastic fan in the bedroom, get and purchase http://www.high-end-motorsports.com/...sun-shade.html
To reflect the uv coming in from the biggest Windows and you'll find it stays rather cool except in the hottest of days. We only boondock, and we've not been limited by less 4 day trips. More than that you'll push it.
Personally the ONLY real bother I have that I wish I would have known or better put, understood BEFORE I purchased was the cargo carrying capacity and towing capacity.
Pretty much all the class c type MBS are almost maxed on the chassis weight WITHOUT much cargo room. Ours has 900 lbs. I think without propane or water. With myself, wife and two kids, and food - we don't carry water anymore (found most places we stay has water fill somewhere or we'll fill up close to where we stay) I would venture to say we're at or over our Gross Vehicle weight.
That would have been the deal breaker for me. Tons of places to put stuff. Especially in the "R" but no weight allowance. Can't leave our kids home, have to pack food, blankets, clothes and chairs. I mean I bought this to NOT "rough camp" anymore so what can ya do? In hindsight if I would have known that - I probably would have gone with the 28' Class A I was thinking of.
Towing capacity is small - 4,300lbs. All of our cars weigh more than that. So now we're debating selling a car and getting a Jeep or something that fits in that weight but it has to fit 4.
Those are my observations. Honestly I love how nimble it is for an RV. We've taken it to tons of places bigger rigs couldn't get into. Parking at the store for groceries, restaurant for food (saves weight) or gas station is so easy. Ultimately that's why we chose it - so well live with the negatives.
I'll say this, I know there will be a time I'll sell it, and get a bigger coach with more cargo capacity. How long? We'll have to see on that one. Do I wish I wouldn't have bought it - no not really, I like it.
