first is keep it serviced twice as often when you are putting that kind of lode on it. dont try to do crazy things and it will do fine.

second put the biggest trainsmition cooler you can on it in addition to the ones you already have.

its a Ford it will handle it

 

With the weight you are hauling and living in the "hills" I'd go for 4:10 rears. Empty if may hurt MPG some but if you are not 65 or above probably not much. But with load will take hills better and maybe a little better mileage. It will lug better without being floored.
If you haul weekly yes the 460 Might be for you . But if just a weekend thing and this is a driver most time the few extra MPG on the 351 will be nice.
