A lot, if not most of the National locations don't rent any of the "Premium or Specialty" vehicles on one ways for some reason. These include the Premium Crossovers, Pick-ups and SUV's with the 8/15 seat vans and full-size crossover as well. With that said see if they allow you to up-fare from the full-size SUV or if your Executive their may be a suburban on the ES.
If all else fails, you would still have the Dollar backup res.
