I do have a 4x4... so 4.30 is not an option for me. No one makes a 4.30 reverse cut. I feel like 4.10 may be to small especially with bigger tires.
There are a lot of good points here. If I upgrade to a bigger, heavier truck, will it make towing more comfortable? Right now I two hand it most of the time. When semis pass I get sucked towards them. My camper weighs more than my truck no doubt. I do have an e2 weight distribution hitch with built in sway Co trol. My options are spend 2000 on my truck in gears, wait for the new aluminum f150 with ecoboost, or the new cummins powered titan ;).
However, a more expensive truck means less money to do our family hobby, which is pulling the coleman and my 20 month old pretty little lady. Thanks for the input guys. I'm leaning towards gears and if I'm revving to high just putting a 33 inch tire on when mine wear out.
