If you have not checked out the MIG Trailer, you should. I have been able to use them and see them in action and they are the real deal. They are small enough to fit down the atv trails, 50" but open up to sleep four adults and can be outfitted with all the ammentities such as running water, sink, furnace, interior lights, etc. etc. All the trailers are highway ready as well so they can be towed by almost any tow rated vehicle, car, truck, SUV etc. When collapsed the tub, floor area also stays available for storage, so there is no need to take any of your camp gear out of the trailer.
I have pulled them with a car, truck, suv, atv, and utv, and they have never let me down. They have gone just about anywhere I have wanted to go including some of the roughest trails in Moab and other areas.
Pretty cool deal. They have done a good job with them.

Check them out on the web and watch some of the videos on youtube. Just search for migtrailers.

 

Can you get these trailers in Canada?

 

Hey JGT

Yes, they have been direct shipped to Canada, and MIG hopes to have trailers in some dealerships there in a few months.
