In Tucson the sheriffs dept shut down the rd up the mtn when it snows because too many dipshits will drive off the road. I really miss driving in snow.
Neither. My dumb ass ran my Fx4 to as nearly empty as possible. Made it to the gas station on a prayer and fumes. Tank held 19.9 gallons before the nozzle clicked off.
I can hear my factory BOV marvelluosly fine with my Injen Cold Air intake kit. Plus the motor gets to suck more air for a given throttle position so more power / slightly better fuel economy (reduced pumping losses) !
Even with the Tow package you will have to supply your own brake controller (wires are already there,. you just have to find and connect them). The Ford Tow package is a tidy setup. I would look into cost of a pro install of aftermarket hitch / harness. Uhaul will do it for about $300
Suspension is a little soft (I like it that way) Not sure what load range tires came stock on your truck. Probly not E's. / 10PR, so maybe pump rear tires up to max inflation pressure. With the trailer you may find the wandering calms a bit.
Lights were factory aimed with the built in rake / downslope of the truck. Camper probly settles the rear a bit, pointing them up. I did a 3" BDS Lift n level and get the same thing you do. I will figure out how to re-aim the lights in good time.
I have used 4wd hi range in heavy rain @ hiway speeds. The truck loves this. On dry pavement with curves the system might build up tension / bind due to unequal wheel travel. If you will drive in mud or snow 4wd beats 2wd any time.
Below referenced vide shows some idiot(s) @ plant did not attach the belt to the actual metal receiver, instead only to the plastic cover. Maybe too much hard drinking / doping the night before?

If I understand the specs correctly, all gears above 7th are "Overdrive", so 10th gear ( 0.636:1 ) is pretty tall. Ford seems to have programed the shift points in D to minimize fuel...
The "65" means the tire is 65% as tall as it is wide. Wider means taller. Going to a 70 series will make for taller tire at same width. Some sports cars (and some trucks) have big wheels and tires that look like black rubber bands around the wheel. This is a picture of a 354/25- 20 tire ...
I see you are not planning a lot of offfroading. In any case Sway bar will impair articulation. The suspension will not flex as easily to follow terrain where the tires are compressed diagonally (eg front left tire on bump / rise, rear right tire on bump / rise)
