our 2012 Entegra Anthem with
Spartan MM chassis will take 5 to 20 minutes to air up before we can move. Been in shop twice to check for leaks. We will loose enough air in a few hours that we have to wait to air up again. after setting in camp for a day or more with jacks set, we loose 1/2 our air which is expected. but the process we have to use to air up is
1) repeat retract all for jacks, 2) dynamite brakes (pump them at least twice, and 3) reset the parking brake....set cruise contol to 1000 rpm... then, wait 5 to 20 minutes for air up. if it takes longer than 5 minutes, then i usually repeat #2 and #3 to try and speed up process.
looking at others comments in other forums about airing up, this is a long time.
very frustrating.
