I have a Runaway Camper and I love it. I put a twin size mattress on the floor and I sleep quite comfortably. Sometimes, I sleep in it in my yard because I like the coziness of it. I'm a single person, so I have the freedom to do that. It's almost like being on a camping trip.
In May of this year, I took it on a trip to Utah, covering 11 states, saving a lot of money by not staying in hotels/motels. When in route, whenever I got tired of driving, I'd pull into a rest area, truck stop or shopping center, for a few hours of rest. When I got to my destination, I would check into a campground.
I did the same thing on a recent trip to California, which was taken during the latter part of August, returning on Sept 11th of this year. I visited some relatives and then it was on to Yosemite National Park. Pulling it with my 2006 Chevy Colorado pickup truck, I averaged 24 mpg, which isn't bad. It handled well going up the mountains, too.
I want to make one more road trip before the winter, not counting weekend camping trips at nearby parks. I hope to go east to The Great Smoky Mountains, which will be my second time there with the camper, and then on to Niagara Falls.
Happy Camping!
