i have the Zinger 18bh. we like it alot. easy to tow with a half ton. I think the extra space would be worth it. I modified some of the storage space and had to go through a bit of trial and error as far as finding homes for items but over all it has been a great camper.
The only issue i had was the A/C was leaking inside the camper early on. You'd wake up with a wet pillow. After taking it to the dealer to have them repair it i fixed it myself. The window style A/C unit has a drip pan underneath it and it is tilted to the outside of the camper. I just made sure the water would flow down hill and out the side. used some tyvek tape to seal the joints and its good to go.
The advantage to the wall mount A/C is if it goes i can replace it at walmart for $100. plus i think the salesman said something about it not being on the roof made it easier for people who store it in garages. Not really concerned about that.
Overall its been a good camper.
