I have a 2020XLT with max towing. This vehicle has been great .. no problems, no issues, mileage is exactly as stated. I pull at 5700lb camper with zero issues. I have had two back surgeries, and I have problem with some vehicles due to the seats - but not the Expy. I have 33000 miles, and just did a 2200 mile road trip pulling the camper. Mileage was low, but that's to be expected.
Everything works fine, no engine issues, no inside issues ... I'm quite happy with it so far, and I have a 100,000 mile Ford warranty as well. I hope it continues to be such a carefree vehicle. Good luck to all of you ..
