Hey Tuga,

Our coach, 2002 Marathon XLII, had the Prevost slides: a single slide. Prevost identified the coach as 1-7450.. Using the 10th digit to signify model year and the last four digits as the sequential number. That shell was manufactured in August 2000 as an '01 shell for a '02 conversion. The current owners who we know have had "Zero"trouble since we got all the "bugs" out of it while we had it for 2 years.
