One big item to consider is not only the towing capacity, but the pay load capacity as well. In 2020 I purchased a F250 super duty to pull our 30 foot 5th wheel. When you figure the pin weight in the bed of the truck along with any cargo in the bed of your truck as well as cargo you add to the rv, it can really add up. I was looking at getting a diesel, however it added $10k to the purchase price and they are heavier in weight (heavier the engine, less payload available). Just check every aspect you can before you jump into a purchase... And be careful what an RV sales-person tells you , they are trying to make a sale. You may want to look at some rv user groups on facebook they are a wealth of information.
