Sounds like you actually may be able to use one enough to justify owning. I’m a diesel person but for rigs less than 38 feet long you do not need a diesel pusher, BUT the closer you get to 37’ the less cargo caring capacity most will have. Because of the higher cost of diesel pushers most are NOT very family friendly. In many of the bunkhouse DPs, the bunks are shoehorned in to a floor plan that does not work very well with the slides in. You are going to have a hard time finding that many seatbelts in any motorhome but especially so in DPs. Good luck, you are going to need it. It’s a lot easier to buy than to sell when the rig does not work well for your situation. Slow down and do not let “end of July” rush you into a poor decision.
Since you are in AZ I would probably buy a used Cruise America class C as your first RV with that many people, but you will be very limited on how much stuff you can put in it.
