I'm at the New Mexico RV, Boat and Travel Show in New Mexico. Yesterday I only had time to look in my area but saw the cutest little camper-trailer. It has a bed, a few places for storage and the back opens to a kitchen area. While there is no bathroom, this little RV is lightweight and can be towed by a very small car. There are options for heating and cooling.
The inside shot doesn't show all the cabinets that some models have but you can get an idea that it is mostly a bed. The Little Guy Trailers are being sold by GT Trailers in Albuquerque. Check their website for more models and information. And come on down and see them plus many other RVs at the show if you are in the area! Jaimie Hall Bruzenak
