Spring chassis maintenance.

[Barrhavencobra]

Hello, I have a hurricane 30q class a. I was wondering what I should have done to ensure the chassis part of my rv (Ford truck chassis and v10 trinitrotoluene engine) is ready for summer. I have done some research and know the following needs to be done, but can anyone either point me to a spring checklist, or provide me additional ideas?

Battery .. check it
Tires .. check dates and then tire pressures
Oil .. have oil and filter changed.
Grease fittings ... if any have them greased
Wheel bearings (I have read a lot about having the wheel bearings checked...thoughts?

What am I missing? I only put about 3000 miles on it last year, if that helps anyone with advice .

Thanks,

Jim
