road turtle Posted June 3 Share Posted June 3 LOVE LOVE LOVE this beast. So far, couple of minor issues. Batteries failed at 38 months. Dealer tested them shortly before that, and declared them good. Replaced with AGM. Front camera just went intermittent, dealer installed a new camera. Still worried about CP4, running Opti-Lube XPD in every fillup. I've started using Blue Def Ultimate due to it's lessened propensity to crystalize. Rear roof trim piece, probably got yanked loose in a car wash. Repair requires removing rear window. I passed, dealer recommended using windshield glue on the trim. Knock sensor went bad, throwing a code. Replaced under warranty. One thing I would love to see Ford change, when using the towing camera, Sync 4 goes into backup mode, full screen camera, voice commands don't work. I wish it acted like the bed camera and would operate in split screen. This thing is a beast, I'm pulling a smaller 5th wheel, fully loaded around 13.5k. It will accelerate going up 6% grades, never balking. I stayed with 3.31 gears, and on level grade, easily goes into 10th gear. Adaptive cruise RTFW, especially while towing. I do wish the transmission would downshift sooner. It loses about 5mph while towing before it downshifts. I've gotten into the habit of poking the throttle when starting uphill. Easily holds the speed. Love the huge fuel tank, 48gal... hate parking the CCLB, it's not fun. Rollup hard tonneau cover works well, but it does take up bed space. I like being able to stand on it. I'd probably go to backflip style instead. Replace tires with Michelin, and they ride a bit better. Quote Link to comment Share on other sites More sharing options...
D3K2 Posted July 13 Share Posted July 13 Did your MPG go down using Opti-Lube? Mine dropped 3 MPG, stopped using and the MPG climbs but not to where it was when new. I still run the stuff, maybe I need to update the new down loads. Quote Link to comment Share on other sites More sharing options...
