All of our camping has been in Florida. Highest elevation is 350 feet. Although we have crossed the Sunshine skyway Bridge numerous times with plenty of power. You did not say which rear end your truck has we opted for the 3.55 for better towing. We chose this unit because its dry weight was 3000 lbs less than the trucks max tow weight. I don't recommend the motorized corner stabilizers. I believe the unit will be more stable with scissor jacks. Electrics will not level the unit. Use blocks under the tires for that purpose. We find the unit perfect for two people and have entertained up to 8 in the living dining area.
