I also seriously considered the Outback, I liked the lay out and the garage.
If I was just using it for fun, I probably would have gone with the Outback too.

Just a little insight to the "enclosed, heated underbelly". The "HEATED UNDERBELLY / TANKS" was a big reason we bought what we did, only to find out different later. It's heated by the furnace ducts (heat radiating from the ducting), and only when the furnace is running. I know from experience, this will not keep your pipes and tanks from freezing if you plan on doing any winter / cold camping. I had the heat pads installed on all three tanks the first winter (after freezing up multiple times). Also, there is no insulation in that underbelly, at least not in mine. So, IMO, what they consider a selling point, should be a mute point.

Like I said, I live in mine year round, and have had to make many alterations to get through the winters (8" insulation added to belly, 1 1/2" styrofoam skirting around bottom, heat tape on all external water lines). I call it the "ARTIC SPECIAL."

Don't get me wrong, I'm not trying to burst your bubble or anything, I think you did great with the trailer. I'm just trying to help out a fellow RV'r. Just some food for thought, before you take the wife and kids up to the mountains.
