Gas vs Diesel for Towing a Fifth Wheel!!!

I don't look at it as a cost per mile thing at all. I got the diesel option cause I wanted it. Same as those who get the Laramie/Lariat option. How about the bigger screen on your radio? The fancier rims? etc. It'a all part of buying a car or truck. Just option it out like you want, drive it until your bored with it and get another.

This speaks volumes. It is not what is better towing a fifth wheel, it is what size fifth wheel you are going to tow and your personal preferences and comfort level.
We recently traded into a Ram 2500 6.4 Hemi to tow a 7700# TT. A diesel for us would almost never make sense as at our age trading out of a 2 year old TT that meets almost all our needs would make little sense just as $9000 for a diesel plus $.75 more per gallon for fuel in our area outweighs all other considerations.
We also lease our trucks now as we get new about every 3 years or less. Have owned vehicles with up to 400,000 miles on gas engines. Some will say leasing makes no sense but it does for our lifestyle, at least our trucks.
For us the cost difference for a diesel is better spent traveling. If you tow heavy diesel is the only option but it comes down to first your needs and second your wants and only you can determine those things.
Good luck.
