We also go to desert... Glamis or Ocotillo when the weather not to hot!, were able to put a dirt bike and two smaller quads in ours, I believe three could fit if you stack them sideways. We love ours, we just returned from a three month outing to the Northwest, and we were comfortable with our 4 large dogs in the garage area. If you need a measurement let me know.
We might have ours up for sale in a couple years. I've had several positive comments and offers on my rig, so they are still holding interested and value.
