Changing gears on a 4x4 would probably be $1500 at best probably more at a deslership.

I use to think that the rear spring was the only difference inbetween 1 tons and 3/4 tons and working at a dealership I have people say " are you sure?". Actually I think on most the difference is front and rear torque or load rating on the springs,torsion keys can vary, brake systems or sizes can be different, and most have smaller tire sizes on 1 tons- thus effectivly lowering overall gear ratio. Also u joint sizes and drive shaft size, material or rating may differ. I cant verify all of this, because every manf. is different, and you cant find every difference, unless you cross vins and look up each part for both.

You will probably have a hard time ever finding a srw truck with axle load ratings much over 6k because most E rated tires are only rated for about 3200lb for singles.

Obviosly you will do what you will, I just like being overly safe than sorry- and I don't want to incur any liability from what I recomend.

Good luck!

Well with a loaded tongue weight of about 1000 lbs it was too much tt for the tv. So out shopping we went. We thought buying a diesel would net us enough payload and towing capacity for a future upgrade. We may have been wrong.
The payload is almost always the limiting factor, not the maximum tow rating. This is true whether it's a SUV, half ton, three quarter or one ton truck. If there's a difference, with 5W you use up payload easier as pinweights are typically around 20% of the camper weight. With TT, tongue weight is recommended to be around 13% of the camper weight.

I have a 2012 Sabre 34RLQS that I pull with a 1997 F250 4x4 Powerstroke with 3:55 gears and automatic. I did install a set of air bags just for good measure but really didn't need them, only running about 25lbs in them when loaded.
Trailer pulls great and actually handles better than my old 28', I am going to change out my 3:55 gears for 4:10's before summer gets here. With the automatic and 3:55's it is just too high geared, unless you plan on pulling at 75mph.....
