Tire pressure question

[tmac0033]

Hi, I have a Livin Light toy hauler. I'll be pulling it with my 2010 Toyota Tundra truck. My Tundra has tires on it that require 33 PSI, all four tires under normal riding conditions. How much air should I put in them when I hook up the toy hauler and drive it across the state of Florida?

To answer that question, the following data is required :

1. tire size and load rating of tow vehicle
2. Exact model of the tundra, including engine
3. Weight of tow vehicle full of fuel and loaded for travel
4. Weight of trailer

Ideally 3/4 taken at same time on a cat scale, with a separate weight of just tow vehicle for comparison.

With this data every answer can be provided for proper inflation and safety.
