Think of it this way:

Imagine a typical (older) car or truck or RV with a solid front axle. When the wheels steer, they pivot in unison on the kingpin on each side.

If the kingpin is tilted fore or aft, that is caster. If the kingpin is tilted sideways, that is camber.

They are separate things, geometrically, but if you are on the ragged edge of handling and traction in an independent front suspension vehicle, they can have overlapping effects, depending on tread design, road crown, etc. But not on a motor home.

Don't obsess over minutia. Level your frame rails and follow tried and proven settings from GM motor home division, IPD or Henderson. They are all close enough that you will be happy.

Will it be possible that when they go to add caster that they could have a problem getting the camber up to were i need it and if this is possible and it does happen are their anything that can be done.I am taking caster from 2.3 up to 6 degrees and than the camber will have to go from -3 up to +.25.could this be a problem for the alignment tech to accomplish.

When the tech aligns the front end he sets both to the mfg setting for the design of the suspension. It varies between kingpin type (on lots of solid axle trucks), to the unequal A arms on many larger cars (including race cars), to McPherson struts. The Tech will move the steering from lock to lock to check the extremes of camber and caster. If it is out of tolerance then a compromise is made to keep the overall action within limits. If it cannot be accomplished then parts have to be checked and replaced. If you want something outside the design of the vehicle you have to replace the parts to change the geometry.

So your saying as long as it is within the tolerance they shouldnt have any problem

Right, but be sure and use a heavy truck shop because many Bear and Snap On machines can't fit a large RV on the lift. In heavy trucks you will find the large radius rods will be welded in place because bolts won't hold them like you see on cars. I did not see what coach you have, but if it is the Chevy P series then a dealership will have the equipment you need.
