Take it to an alignment shop to have frontend parts checked out and get it an alignment.

Check tire pressure. Over inflated tires can cause wondering. Especially on the front.

Common problem. Take it to a shop that specialize in alignments. You need to have the caster adjusted to a range outside of the factory specs. This WILL NOT increase tire wear.

Ask your shop about the need for a bushing set.
I had to add a ford bushing set in order to properly spec my E450.

Do you have experience driving similar long-wheelbase vehicles previously?
While it's certainly possible that the alignment needs adjusting or some suspension parts are worn (both are quite common problems), it may also partly be you not being used to how the vehicle behaves. The natural tendency of many people at first is to overcorrect because it takes longer for the vehicle to respond to steering adjustments. Sometimes the solution is as simple as consciously looking further down the road and perhaps trying to make more gentle steering inputs to keep in the proper lane position.

Most of the above can be true, however there are things that you need to check first. Yes I own a 12 aspect. Check tire pressures, do not use the 75psi on sidewall or whatever is on door jamb. I run mine at 60-65 for fronts, 70 for rears. Depending on load what airbag pressures do you run? Again mine is 55-70 again depending on load. Have you weighed the rig mine comes in around 13500 we travel light. 1/3 tank water, empty black/grey tanks (all located over and back of rear axle).
When 1st got ours it did wander but I had to experiment with the above settings to get it to stabilize. I have new shocks to install and I got a new steer stabilizer but havent gotten around to putting on since we are not going to travel again this year due to the virus.
There was a road test back around 10-11 on the winnebago and these were also complained about, however I havent been able to find it since I read it years ago.
PM me if you have questions

I drove a 31ft 1996 Safari Trek for 4 years (P30 chassis), a 40ft 2002 Newmar Duchstar for 15 years ( Spartan chassis) sold it in 2017 with 106K miles.
I will have the camber checked and form what I'm now reading , I will add a safe-T steer, Billstein shocks, and sway bars.
It has air bags but the previous owner rode it with only 25 PSI and I will increase to 40-50 PSI
I had the tires inflated to 55- 80PSI front to back. before I drove it home.
Thnaks for your input and I hope this all works out.
I love the fiberglass roof and interior quality of winnebago and think it's second to Coach House and Phoenix Cruise of that era.

Friend of mine had a Winney with the same issues. He bought an after market steering stabalizer and installed it himself. He was very pleased with the improvement.
