Hard sided campers under 1500lbs with 6' int ht spreadsheet.

Sorry, its PTU,on every AWD vehicle. I fixed my post. For about 20yrs, Ford made their PTU too small and jammed it in between a hot engine and hot exhaust manifold, so oil fails prematurely. As long as the oil is changed, then I heard there is no problem.

I just found out that on the tow package MKX's rated at 3500lbs, use the same PTU as my standard non tow MKX, so maybe I'm just paranoid.
