I had a 96 Warrior 30 RQ.
The chassis battery was not charged by shore power. The chassis battery would discharge in three weeks or so if the engine wasn't ran due to keep alive current drain for the engine computer, radio and other stuff.
I bought a Battery Minder float charger that kept the engine battery up as long as I was connected to shore power. It is now in my present motor home.
I had some front end parts replaced and an alignment done and it drove fine. There are two bell cranks on the front end that tend to wear and can cause a lot of wander. That is something to check.

On mine the RV park cable input was not easy to find. The original owner showed it to me. It is in the service bay on the left side on the ceiling.
The vehicle owners manual described how to set the pressure in the airbags. In case you don't have the manual this is what mine said:
The owner’s manual gives the following ranges:
4,300 LB front suspensions = 10 psi to 50 psi
5,000 LB front suspensions = 40 psi to 50 psi
5,300 LB front suspensions = 50 psi to 80 psi
5,500 LB front suspensions = 60 psi to 100 psi
For the proper adjustment it says to inflate the air bags to the maximum pressure for your vehicle, load the motor home, park on a level surface and then reduce the air pressure as needed to level the motor home but don’t reduce it below the minimum.
I have seen other schemes for adjusting the pressure per ride quality, but the 1995 Chevrolet Forward Control Chassis owner’s manual said to do it as shown above.
I don't know if it's accurate or not but other posts have said the pressure in the bags affects the alignment and you should have it checked when you get the pressure set. The manual did not mention that however.
