The right equipped F150 3.5EB engine will handle the 7600 gvwr trailer just as well as a F250 gas.
Warning about Fords F150 max tow option. It does nothing to increase max payload or max tow ratings..
Ford has several F150 packages from a:
#1. 7850 gvwr...4800 rawr....2500 lb in the bed payloads.
#2. 7600 gvwr...4550 rawr... 2200 lb in the bed payloads
#3. 7050 gvwr...4050 rawr... 1800 lb in the bed payloads
#4. 6800 gvwr...3800 rawr...1500 lb in the bed payloads.
All F150 above can have the max tow option which basically 3.55 gears.... 36 gal tank..... big rear bumper.....integrated brake controller/etc/etc which is a must for towing.
Just choose the right F150 platform for a 7600 gvwr trailer.
