If you are looking for a topper or small camper with some class, check out Casual Turtle Campers.
From the website:
The idea for Casual Turtle Campers was conceived by Peter Pavlowich in the summer of 2010. On a road trip to Colorado, he noticed an abundance of truck campers but a profound lack of variety or style. As a Wood Construction and Design graduate from the University of Idaho, he believed he could design and build a simple and attractive alternative to the big, heavy, white boxes that he seemed to see everywhere. Over the next few years, Peter slowly and methodically brought together ideas and drew up plans for what would eventually become the design for Casual Turtle Campers.
He very happily lives in Fort Collins, Colorado with his wife, Lindsey, and their dog/shop foreman, Moxie. We love when people stop by – just get in touch!

Those look really good, do you know if there are any distributors for these over in the UK?
I doubt there are any “distributors”. I think it’s just an artisan and his shop. Call him up and see.
Thanks Paleotool, I’ll get in touch and see what he says
More good stuff, right up your alley!

Don’t know how you feel but I have a visceral reaction to the “paleodiet”, so was glad to see someone with credentials debunk it. Just call it what it is, the ” I love to eat red meat” diet and leave the paleolithic out of it.
