Dreadnaught,

That's great. Be sure all updates have been done, including Prevost updates. We have recently learned that vintage of XLII shell, a few, had some delamination of the steel layers in the ceilings of the slides rooms. There needs to be some support structure added and the delamination repaired. Apparently a thinner steel was used in the slide room rrof that is not holding up, We learned this from a previously owned new coach owner, The Tiger Coach, Marathon #884, that was featured on the Travel Channel a time back. Its an '05 as well.
Also besure to have the front bushings checked, and look for front tire wear.
The "Tiger Coach" has about 18,000 miles on as of 9-07-06, and needed bushings, tires and an alignment,as well.. Hope this doesn't dissuade you. The coaches with the 365 tires ride superbly.
Keep your eyes open and be informed.

Good luck
