I have my 7.3l there in line to be re built. They do a lot of 6.0 and may have 6.0 long blocks in stock if the 6.0 ARP rod bolt backorder has been resolved .

Appreciate the feedback. You’re correct probably closer to 6-6500 with trailer, fuel, etc. I recall checking a couple years back and pretty sure it has 3.42’s in it. I did have a local tuner flash it over the summer and it definitely tows better, but it still was at 4-4500 rpm on the rolling hills. You think a set of 3.73’s would help to give it a little extra grunt and not necessarily need to downshift? I don’t mind taking hills at 55, but it didn’t seem to matter to the truck my speed, it just wants to keep the RPMs high towing up grades.

I was looking at whipples yesterday and know that would do the trick, but it comes at a cost as well. Maybe I’ll start with gears and see how she goes. Already laying the groundwork with my wife on why a whipple “just makes sense” 😂.

After receiving my personal property tax bill yesterday on a 10 year old truck and 8 year old minivan, no F’ing way am I buying a new truck. The county was kind enough to adjust used car values with the current market.

Thanks for all the input from everyone! Definitely helpful for factoring in a decision.

If you are concerned about durability, don't do that! The engineers that designed your engine spent a lot of time testing the powertrain under a variety of conditions, including towing. The engineers put more strain on your engine during testing than you are likely to do while towing. Modding the engine puts stress on the engine beyond what it was designed and tested for. I would leave it alone, and just drive it.
