Looking for opinions. At what amount of use does one think that they should go to a heavier truck. I have a 2015 F150 with the 5.0 V8. I have about 50,000 miles on the truck. They have where it shows the amount of miles that you have had a trailer hooked to the truck. Right now I'm at 10,000 miles alone dragging the trailer. The biggest amount of that has been to pulls. Trailer weighs about 2800 lbs. and usually with weights and tractor I have about 6300 lbs. on top of the trailer weight. When I bough the last truck I came close to buying an F250.My last truck had about the same use and I had the differential carrier bearings getting noisy with 106,000 miles on my 2009 F150. My thinking is to bite the bullet and go to an F250. Hate to give up the gas mileage of my F150 when not dragging the trailer. What's your thoughts. Thanks for the input.
