A 3/4 ton truck will work, as long as you don't get a diesel. The diesel and assorted coolers can take up to 800 lbs of payload, leading some 3/4 ton trucks with less payload then their 1/2 ton counterparts. Also, as others have mentioned, a 3/4 ton truck will limit your "future" RV purchases.
Others have commented on GM trucks, which I am not familiar with. Those and RAMs should be good choices, but I will chime in on Fords.
I have a 2017 F350 4x4 Lariat CCSB with the Power Stroke. It has been an awesome truck pulling my previous Reflection 5th wheel across the USA several times. Even with the Cargo Carrying Capicity at 3426 lbs, I was getting close the GVWR when the 5th wheel was hooked up. There were no air bags of spring helpers needed with my setup.
The truck now pulls an Imagine travel trailer. Overkill maybe, but no use getting rid of a perfectly good truck.
I might have considered the 7.3L if it had been available in 2017. Our Fire Co has a 2022 F250 with 7.3L and 10 speed for our utility truck and that does great job pulling our boats and UTV..........but there again it is not the weight and frontal area of a 5th wheel trailer. Also, some 7.3L engines in that time period had delaminated lifters, causing engine failure. I think that problem has been corrected in the newer models.
I have been totally satisfied with my Power Stroke. Just a bit of extra trouble with DEF, draining the water separator, and more expensive maintenance, but it is worth it to me. Pulling our 5th wheel up and down the Appalachians and Rockies were not a problem.
Some advantages of diesels:
You can use the "big boy" truck lanes when fueling. No problem getting in and out of those
Both the power uphill and the engine brake downhill are awesome
You do not loose power at altitude because of the turbos
Better fuel economy
The cons of diesel:
Expensive option
Heavy
Fresh, clean fuel needed
Fuel more expensive for now
From the forums I am on, I have never heard anyone say they wish they would have gotten a 3/4 ton truck instead of a 1 ton, but plenty of the other way around.
