So assume the "P" rating may be the issue? Also tires are inflated to 35psi and the sidewall states max psi of 44psi. Do you thing I should add a little more psi's? These tires are like new. I hate to buy new LT's but if its a safety concern then I might just have to

The P tires are a contributing factor, not enough wt on front and not enough caster are all contributing.

FYI, a 1/4 -1/2 increase in caster over factory specs will do wonders for a wandering problem.

Would definitely run them up to max if not to 50# just to try it while towing, especially on the rear and at least 40 on the front for towing. I would let them back down to 35# when not towing as the ride will be horrible.

I doubt caster is off at 30k but maybe.
Excessive tounge weight resulting in high front end pitch will throw it off tho.

Might not be, I always have them increase caster at least 1/4 over factory. I think on mine it was L +4.10 & R +5.1 and we increased both +.25.

Boy! Dealing with this is going to make me crazy. I never had to worry about with my GMC Sierra with the Duramax.

Thanks again for the help and suggestions

I agree will all the above but also is the hitch set up correctly & is the trailer level (or close ) when it is hitched to the truck. I had a similar issue with my 22' box trailer but it was the hitch set up.

All my issues went away when I got a truck with training wheels

The above suggestions to scale is a good idea the ratings on the tire are not the best for towing:
Goodyear*Eagle LS-2
Along with the lower rating when used on an SUV per Tire Tech Information - Tire Specs Explained: Maximum Load :
P-metric tires used on passenger cars and station wagons are rated to carry 100% of the load indicated on the tire's sidewall (or listed for the tire in industry load/inflation charts). However, if the same P-metric tires are used on light trucks, (pickup trucks and sport utility vehicles for example), their carrying capacity is reduced to 91% of the load indicated on the tire's sidewall.

In the mean time I would run them at max sidewall pressure while towing until you can work out the number etc
