On our first big trips we ended up in a campground next to a prevost motorhome. In our wee little vintage trailer, watching TV on the laptop, we were amazed to look out the windows and see this behemoth that was longer than our whole rig combined, with multiple slideouts, and we could see a huge flatscreen tv that looked bigger than our tv at home
Basically it looked nicer than our house, but on wheels!
We have often talked about the pluses and minuses of TT vs MH. The thing I keep coming back to is that as long as the TT will roll, you're good. If your MH breaks down you have lost your transportation AND your living space. With the TT you could always camp out and send the tow vehicle to be fixed. And of course anyone can replace a tire on a TT or a tow vehicle. Plus most MH end up dragging a toad everywhere they go, so right there you've added back the complexity of hooking up and towing something.
I'm still a little jealous of motorhomes though. They seem to have some really nice features, and I think for long trips it would be nice to get to your destination for the night, park it, and have everything ready to use, instead of spending the time setting up the TT.
