As indicated, Toyo recommended pressures are:
Left front: 100
Right front: 75
Left rear: 85
Right rear: 90

Also loks like you need to try to move some of the weight off the left front if at all possable. While certianly not over weight, almost 1000 lbs diffrence on one corner is a lot especally on the steer axle.

I'll see if I can slide the generator over a few inches...

How far do you think you'll need to move it?

FWIW, I was having a similar issue as described here. I found that the used tow bar I had purchased was allowing the toad to move around enough to cause a lot of the grief I was experiencing. An adjustment here and an inexpensive part there made a VERY notable difference! Just thought I'd pass that on....

I haven't seen anybody ask if the ride height has been checked.
We had a 2001 Journey that wondered, after the ride height was properly set along with an alignment the wonder went away.

What was the Journey "wondering" about? How did it communicate it's thoughts to you?

P.S. Seriously to the OP; Your issues with your TST system is most likely due to the use of the extensions. It would be nearly impossible to get a good seal with so many points of failure. Get some long valve stems installed and your TST system will surely work.

What's the correct ride height spec? I wonder as I wander...

There's a process for checking ride height spelled out pretty clearly in the P-30 chassis manual I was looking at. Not sure if that means there's one for every chassis or not?

The coach/chassis is parked on a reasonably flat surface and dimensions checked at specific points on the chassis to see if they're in range. I can only assume this would be done only after determining the coach is within the gvwr/gawr range.

Most alignment shops that are RV friendly will do this for you when performing an alignment.

okay...enough is enough. forget about all of this camber and caster, corner weight, steering correctors, stabilizer crap. you are driving an air filled box down the road at 70 mph which is the equivalent of a level one tornado. a 130,000 pound semi is going to blow you sideways no matter what. and a 60 mph crosswind is going to give you a major case of white knuckles and strip your awning off every time. before you spend the thousands of dollars these people are suggesting, just slow it down and enjoy. if it still scares you sell the damn thing and buy a lincoln navigator. remember every video of a major destruction in a tornado is in a trailer park. no matter what you paid...you are driving a trailer with a motor. case closed. this s..t is supposed to be fun. if it is not for you get rid of it.

one more thing...it is designed to wander. if your coach didnt wander even the slightest wind would flip it like a pizza box in a thunderstorm. grip the wheel with a minimal pressure, ease it over to the right sideline and breathe deeply. bottom line...the tighter you try to make it the more dangerous it becomes. as a former nhra top fuel driver i can assure you that without wander i could never have driven my ride 297 mph in 4.5 seconds without a heart attack. i have a 1993 airstream land yacht with a sloped front. i always feel like i am crawling.

If you read the OP's first post you'd know that he had a good handling MH which went south at some point. So, something is wrong and needs to be addressed. While all you said is true to a point, one should not ignore severe handling issues. MH's being a handful in the first place (as you correctly state) require careful setup with regards to alignment, tire pressure, weight loading and distribution, etc. The OP has at a minimum tire pressure issues and weight distribution issues, possibly a bad tire and possibly a bad alignment. Ignoring these issue is dangerous and NOT fun.

[buki]

excuse me but severity is a relative term. for most people having to turn the wheel at all is terrifying. inflate the tires in accordance with the tire mfrs suggestion...no more no less. trying to adjust handling on a moho by screwing around with tire pressure is unbelievable. amatuers have no concept of heat inflation or stagger. it is NOT the physics of the vehicle. it is the idiocy of the driver. going south is something i do every winter. it has NOTHING to do my asphalt chariot. automobilist is very obviously in way over his or her's head in the whole moho experience. my final suggestion...let someone else drive. that will cure all of your fears.

I'm sorry, but I don't see how that statement is going to help the OP.

I see you're new to our friendly forum. I say friendly, because most folks in here are...
