Our toyhauler has 50 amp electrical but we rarely get 50 amp service to plug in to. It does fine with 30 amp, runs the AC, fridge, microwave, furnace, lights, water pump, battery charger, whatever we are using. You just have to have the correct adapter plug to go from 50 to 30, available at any RV place or WalMart carries them.
The pads at the sites are gravel, compacted crushed limestone. I think you will be fine.
Flying J at Peculiar has the dump station and fuel (gas or Diesel) in one drive thru location for RVs.
