I just assumed it was a toyhauler because KZ is widely known for it. In fact the majority of the ones at my dealership were haulers. Bad assumption-sorry. Still, they are constructed the same way. There are a few options I would recommend, though, if you have the choice. We were able to order it with an extra fresh water tank and that helps tremendously when dry camping. Don't know if they offer that option on all models. Also, the standard 6 cubic foot fridge is a bit tiny, so see if you can get the 8. This holds true for the 6 gallon water heater as well. You can have them put a 10 in there. Of course it will be a bit extra $, but if you don't do it and then decide you want it later, then what?
It was easy for us to order these things because our dealership encouraged its customers to factory order exactly what they want rather than buy off the lot. This makes the customer happy and keeps the dealer from having to have tons and tons of inventory on the lot. He said the KZ factory is usually willing to do just about anything a customer wants, even if it is not on the order sheet/options list. He was right. The 10 gallon water heater was nowhere to be found in our paperwork, but I had the dealer ask anyway, and KZ was happy to do it. I suppose each dealer is different, though, and you might be buying off the lot. In this case see if the dealer has one with some of these other features. Either way, I'm sure you'll like it.
Good luck.
