karebear - The coach battery should have a useful life of 5-7 years. Mine stays charged while stored over the last 3 winters.
In general - replaced my front shocks with "bilstein be5-2480" and cross rotated my tires from the fronts to the rear outside duals. The quietness of the ride went from a barely audible rumble as the cupping part of the tire hit the pavement to total silence. Had 23,000 miles and felt that maybe it was time to switch to lifetime guarantee shocks.
