I am soon going to be looking to buy a new/used truck to tow my 2011 North Country 32 ft. travel trailer it weights 7500 lbs dry , I am looking at an F250( I Am a Ford guy) but not sure if a gasoline engine would perform my needs or do I need to look at diesels, I live in flat Florida, but I plan to make at least one trip out west and up north right after my retirement, after that I will be doing most of my camping in Florida and south Georgia,(all flat land) . currently Iam pulling with a 2005 Dodge Ram 1/2 ton with a Hemi and it does very well here in Florida, but I want go where I would need to climb hills with it. Diesel trucks cost more to began with, an the maintenance is more expensive, Money is an issue but I can, if need be, purchase a new/ or slightly used diesel, but after my big trip around the country I Am not sure I will need the more expensive diesel and will be lift with the higher cost of the maintenance and the higher fuel prices. I hope you more experienced guys will convince me on one or the other, Gas or Diesel?
