We are thinking of buying a 5th wheel and are impressed with the K-Z Sportster with the 6ft storage room in the back. We have mountain bikes a motorcycle and a small ATV to fit in the space with a loading ramp. We liked the idea of the storage and luxury of the living area. Does anyone have any other models that come up to the standards of K-Z models? We will be winter wonderers in the southwest. Any suggestions would be appreciated even if the comments are negative. Best to learn before we purchase.
