Please don't give up on me...still need help!

Ever ride a motorcycle? Bike riders rake the front forks so it will steer better. Once they rake the front forks you can ride down the highway without even touching the handle bars. On a vehicle with 4 wheels it is called caster. Basically a frontward angle of slope of the front wheels. I suppose if you could could give it enough caster there may be increased wear as you turn a corner. I doubt you would even notice the increased wear with a 4 wheel vehicle. Probably you would notice it on on a bike with an extreme rake, called caster. When I spoke to the RV people that install front end products they all said RVs need more caster than factory specs. Most alignment places set vehicles up to factory specs. MHs need more.
I suppose weight on each wheel has some effect. Being a practical person, I don't weigh each wheel of my MH every time before I drive it out of my driveway. If you know you have more weight on one side or in the rear you could compensate. I guess by the feel of the MH. I suppose if I tried to tell my DW where we had to store everything or had a 4 wheel scale installed in my driveway I'd probably be in divorse court not RVing down the highway. :B JMHO
