Anyone pulling a Montana 3120 with a SRW short bed?

I know this is getting off topic for OP, but I have 1400# of tube sand over axle, 60 psi in stock tires. Guess I could lower them more, but now that winter is winding down, no need to.

Even with 30-35 psi in the rears you would still have more carrying capacity than you have with the sand in the bed. I run 30 rears on my RAM DRW when not towing year round.

Take a look at your specific tire size and load range weight/inflation chart. I used to run less than 60 with 4,500# pin weight.
