Gpa looking for Diesel!!

[JMalmy21..00/7.3]

Gpa is retired and my Gma is about to retire. He has a 32 foot 5th wheel (just under 10K lbs) and is going to be driving it around the country stopping of anywhere for a few months at a time. Currently driving an I-FORCE Toyota Tundra. Wants to upgrade to a diesel for the towing ability. His current question is..... 7.3L? 6.4L?? or 6.7??? Doesnt want to spend a buncha money to upgrade in order to optimize his truck for longevity power and performance?? Suggestions???

Start with researching the purchase price of the vehicle. You could buy three 7.3L trucks for the price of one 6.7L truck. I can't imagine someone being in the market for both vehicles.

me, my pops, my mom, closest family friends and sister bf....we all drive 7.3.. he just wantd to buy a good truck. in the market for dodges too. He is just "in the marker" in general.

If they want creature comforts etc probably the 6.7. If they want to go a little more rugged then the 7.3 or 5.9 I would say.
