I technically don't have a trailer right now, but my buddy parks his in my driveway and in return I can use it whenever.
I would love a toy hauler. Having a wife and kids they aren't real excited about sleeping on an air mattress with no access or heat or ac or pretty much anything and they would like to go on longer trips with me, maybe even extend some trips. Jennings could turn into Disney for example if you extend the trip for example. I was hoping to get one this year but my old truck went TU and I got a new one instead of a toy hauler for this year anyways. Also we have lots of camping trips planned that we would love to have a camper for, Yellowstone, Yosemite, Grand Canyon etc...
But yes there are certainly cheaper ways of getting to the track, Ryan showed us that with his Saturn. But last year Ryan, Brandon and I went to road atlanta and back last year and I think between the 3 of us it was $70 a piece for fuel, doing 20ish days a year that helps out. So more than one way to skin a car I suppose.
