Dog tracking
Have any of you ever experienced dog tracking. When Im driving down the road, the rear end of the coach is 10-12 inches closer to the centerline than the front

Assuming your shocks,tires and pressure,alignment,front bearings are in good order,may be your torque rod bushings.Others will soon chime in.

For one reason or another your rear axle isn't parallel to your front axle.  You sir, have a problem.  It's repairable but it needs to be addressed.

Check bushings, and also bulkhead. Could be serious so don't wait.

2-6 in  is pretty common. 6-10 is too much. Should be easy to find . Measure the tire gap to fenders and go from there.

Stay away from toll booths and road construction between Jersey barriers.  How do you get fuel at truckstops?

Mike,

Can you give us some more details like:
did this happen all at once (like something broke)
has it been getting worse slowly (like something wearing out)

Can you post some pics...

I can't help but wonder, where did you measure this discrepancy?
Was it in the rear view mirror? If so, its an optical illusion. Perhaps, I am just naive but your distance off just seems to be very unrealistic.
OR, are you all putting...

Not to make fun of his problem but has anyone heard that term before?

Just to underscore the seriousness of this problem, here are two quick tests.

1) at about 30 MPH take your feet off the pedals and pull the parking brake.  If the rear axle doesn't come adrift you're good to go.

2) Find a grade crossing on a down...

In the days before 4-wheel alignment machinery, dog tracking was a symptom of a bad collision repair.  Slight dog tracking...

Agreed-- it may be something complex/difficult.

But, I always start by checking the easy/cheap things first.  Bushings, bushings, bushings.  If play in them the axle is no longer located where...

When we first got our coach we noticed it was a little difficult to steer.

Rudy Legett recommended an alignment shop called big truck alignment which is located at 515 South US Highway 69 in Huntington Texas. Their phone number is 936-465-0701.
