Is there a Diesel or Gas break point?

I'm strongly considering upgrading to a 250/2500 or larger truck and I was wondering if there is break point where diesels just make more sense than gas. I know that as a rule diesels are better at pulling heavy loads than gas engines, but they also come with added maintenance costs. So I was wondering if there was a trailer weight where it just makes more sense to buy a diesel. If so, what is it?

We currently don't own a TT, but we've been looking. We first started looking for something my existing truck could pull but we discovered that its not a very robust tower, so we are in the market for a new truck. Since this would be our first TT we don't want to go too big, nothing longer than 29' and no heavier than 8500 lbs GVWR. Some have told us to buy the truck, then fit the trailer to the truck and others have said buy the Trailer and buy the truck to fit it. Its basically the old chicken and egg debate. So we're trying to both at the same time.

Lastly, I've noticed locally that diesel fuel is generally more expensive than regular gasoline, but I don't know if that's true around the country. Is it?

The cost part is largely a wash. You'll pay more up front for the diesel and a bit more to maintain it, but you'll spend a bit less on fuel and will have a more valuable truck on resale. In the scheme of what you'll spend on either the cost difference isn't really material, imo - make your decision on other factors.

FWIW, diesels are better at pulling any load than gas, not just a heavy load. Diesels are also better at moving an 8000 lb truck around without a trailer.
