We just out of a motorhome into a travel trailer. If your plan is to roll a lot and see the country the motorhome might be the better choice. But, if you plan to travel and stay in one spot for a while before moving on then the TT might be the better choice. The motorhome had a lot of storage, way more than the travel trailer. The motorhome was fully self contained in all kinds of weather. The generator would run for days on a full tank of gas, like three and a half days or so..maybe more depending on how hard it was working. And that still leaves like, 1/3 tank of gas to run the motorhome to the gas station. It's great..except that if you don't use it a lot it's a lot of wasted cash. 7 tires = $2,700.00, 2 oil and filter changes, Insurance, 9 miles to the gallon, lube the chassis, brake jobs, exhaust gaskets, etc, etc.. I liked traveling in the RV but, that whole drivers seat area is wasted space at the campground. That's where we kept the dirty clothes bag.. So, we had a 28 footer. The usable space was really about 23 - 24. The motorhome would cruise down the interstate at however fast you would like to risk it and while pulling a toad.
We had a TT years ago and have the current one. I don't really like towing all that much. But, when it get's set up at the campground it's a vacation home. It acts more like a home, feels more like a home, etc..
I think that Subaru will have to go. It won't tow anything worth doing any extended camping in very well. You may also consider a class B van. It's kinda hard to know what you like till you've tried it. At one time we had a cabover truck camper. It was awesome for what it was designed to do. But, I can't see ever doing that again. Crowded, kinda like luxury tent camping. In the TT my wife can go to bed and I can stay up and watch TV, whatev's.
