We purchased our 16 BH in the early spring of 2010. Have camped in it quite a bit locally as well as several long trips.
1. We tow with a 1999 Jeep Cherokee. It has an in-line 6 cylinder engine. We usually get around 20 mpg not towing. When we tow, we average between 12 and 13.5 mpg. I also tow not using overdrive and keep the speed around 55 mph. We are more than pleased with how it tows going down the road. We did get a weight distribution hitch as well as anti-sway tho.
2. We also put our heavier items in the back of the jeep. There are just the two of us, so we put the bacik seat down for more storage area.
3. bought a small step stool to access the top bunk. Also bought good foam mattress toppers for the bunks. Very comfortable.
4. A/C was more than adequate for us last summer.
5. We did flip our axles. Had no derogratory effects on towing. It was very good for emptying our tanks tho. We did keep our 14″ tires. They worked just fine for us.
6. The price just cannot be beat for what you get in these units. You will find that after you get the unit, that you will "tweak" it a bit from time to time to make it 'yours', so to speak. If you look throughout the forum, you will get some great ideas from what others have done.
Do not hesitate to get this unit if you feel that the floor plan suits you. KZ has done a good job of putting together a very basic unit with all the things we want.
