2011 Ford Super duty 6.2 3.73 tow 10k+?

Hi everyone,

My wife and I bought a toyhauler and are looking to upgrade our truck. We have a 09 f250 crew cab short bed with the 5.4 and 4.10 gears. It pulled our former 27 ft travel trailer well at about 9k fully loaded and even with a 600 lb utility quad in the bed.

The toyhauler (07 Raptor 3110 TT not 5th wheel) we bought is 9200 empty and has a gvwr of 13k. I towed it home from the dealer and the 5.4 did ok at under 60mph but when i turned onto the interstate 65 - 70 what a stuggle but we had a hard headwind (trailer was obviously empty since we were bringing it home from dealer). We bought the trailer assuming we would look for another truck.

I like the 6.2 and we are looking at used but the 4.30 gears seem impossible to find used or even new for that matter. I have test drove a few 6.4 psd but the fuel and maintainence cost concern me especially if it breaks down. I have been reading through post in the 6.2 all week and have found plenty of people that town heavy with 6.2 and 4.30s but not too many with the 3.73. Will the manual shift option make up for the taller gears by not using 6th gear? or will it feel underpowered? I understand that it will likely be in 1 gear lower then the 4.30s on hills but concerned that it will run out of power when pulling heavy since the towing capasity is only a few hundred lbs more then my 5.4 (11700 vs 12000) but the 4.30 are rated for around 15000. We usually camp within 3 hrs of home but have alot of hills in my region (WNY and Northern PA) but would like to go to some of the offroad parks in tn ky and wv 8 to 10 or so hrs away. Im not concerned with empty mpg since i have another vehical that is my dd. towing power is more important to me then 1 or 2 mpg. But if the 3.73 will do the job better fuel economy is never bad.

I have not driven a 6.2. We found 1 we like at a good price but it is 5 hrs away and dont want to waste our time to go look at it if its not up to the task.

Thanks for your help
