My TV is a 2010 F150,SuperCrew. 5.4 liter with 3.55 axle ratio. It has the trailer towing package which adds transmission oil cooler and radiator upgrade. Also have electronic trailer braking and weight distribution hitch.
Pulls, accelerates, and brakes great. Only issue is the MPG which drops to about half (or less) when I'm towing our 2503s.
I don't know our loaded cargo weight but the wife and I aren't ones to travel light. The truck bed is loaded up with ice chests, chairs, etc.
Tip. Get yourself some cabinet corner safety cushions. The upper cabinets by the bed have sharp corners. Otherwise we love our MiniLite 2503S and will be heading out Friday for our third straight weekend trip.
