tire pressure on tow vehicle
should I increase the rear tire pressure by 10 psi, on my truck's tires or leave at the suggested 35 psi that is shown on the sticker on the door jam?

My little truck ( Nissan Frontier ) has "P" tires. Normal inflation is 35 psi. Max on the sidewall is 44. I tried 44 on the rear while pulling the trailer and discovered that was over-inflated. Even loaded up, the outside rib of the tires was not touching the pavement.
I settled on 36 front and 38 rear in my case, and this seems to work well. The truck handles correctly, the tires wear evenly, and run cool even on hot days at highway speed all day.
Y'alls mileage, tires, pressures and experience may vary.
As for "squishy handling", the biggest change I noticed regarding that was removing the load range C ST tires from the trailer, replacing them with load range D LT tires. Much better towing experience.
EDIT: another improvement to the stability of the towing with this combo was replacing the OE shocks on the back of the truck. I installed monroe sensa-tracs at first, and they were an improvement. I have since replaced those with billstein 5100's, and those were another step up in improvement.
