After looking at lots of late model XL shell coaches, one difference between most of the Liberty and Marathon conversions is the amount of A/C and heat. Many of the Marathons have 3 Cruiseairs and 40k Webasto, while the Libertys have 4 cruiseairs, 80k Webasto and OTR air.
I understand the difference b/w the OTR and non OTR systems. My question is are 3 cruiseairs enough to cool a 45' bus in hot weather while camped? Is the Liberty system overkill and Marathon sufficient or is the 3 Cruiseair setup marginal?
