Congratulations on your "new to you" Jayco! Great choice! Mine is now 10 years old and the membrane roof material is as new. I went up 2 days ago and resealed everything for the upcoming winter rains, lubed the antenna lift system, and gave it a passing grade!
Dicor makes membrane roofing systems, from their website "Beware of areas where fruit, tree sap, or harsh environmental fallout may stay on the roof for an extended period of time. These conditions may result in permanent stains." And don't use anything that contains any ammount of Petroleum Distillates in it on the roof! Period!
Remove the tires and store them if possible covered away from electrical devices such as pump motors which produce rubber destroying ozone...and moisture which also kills rubber. Use something like 303 Aerospace Protectant...nothing made with a petroleum base.
These jack stands will level your Jayco, support it and keep it stable...use square ABS pads under the jacks to keep them from sinking.
Jack StandsYou will love your new Jayco...we've had 7 of them...no problems at all with any of them. Quality thru and thru! Have fun and enjoy it!
Your Jayco!
Here it is!
