When Rick Allanson and his wife, Brenda, gather with friends or relatives, it's often at their 30-foot travel trailer, not at their Edina home.
Except in winter, an RV park on the Mississippi River north of the Twin Cities is their home away from home.
"Everyone loves to come to the campground to barbeque, have a campfire and make s'mores," Rick Allanson said. "We're there almost every weekend. It's a getaway."
A getaway on wheels.
Longtime campers, the Allansons are passionate recreational vehicle enthusiasts.
And they are not alone.
Nationwide, about 8.9 million households own RVs -- the highest ever -- according to a 2011 University of Michigan survey. That's up from 5 million 30 years ago.
In Minnesota, about 150,000 trailers and motorized recreational vehicles were registered in 2011. And that doesn't include pickup campers, which aren't tracked because they don't need special license plates.
