For that size trailer a 3/4 ton Gasser will do the job just fine. I had a 12000 pound fifth wheel and towed it with a 2014 6.4 liter hemi and it did a great job. The new ones would be even better with the new 8-speed transmission.
That said it is always cheapest to keep the old truck and fix it. The new diesels will tow even better than what you have now. All depends on how much money you have to throw around.
Agreed.
I towed the same 10k TT with a 2015 F-250 6.2L and a 2018 F-250 6.2L and even those were miles apart in performance.
