Travel conservatively. An AS tows well - sometimes too well and folks drive too fast. Learn before you fly. Towing is an all hands on deck, 100% attentive driving activity. Travel shorter distances than you would normally plan to drive. There is more work to AS travel than car/motel travel.
Read your manuals - then read them again. The videos do help .... Long long Honeymoon and the Colonial demos are quite helpful.
Test your systems. Learn how to make the control for the AC/heat to work for you. Same with entertainment system.
Clean and Wax your trailer regularly. Store inside if at all possible. Do not tarp it. Inspect for leaks and cracked sealant that might resut in a leak. It should last 3-5 years, but inspect it every year.
Don't leave the trailer unattended with the awning deployed. Strong winds can rearrange the supports in short order. Don't deploy it level when you expect rain. The water needs to drain off or it will overload the fabric and supports.
Carry your salesperson's and the service manager's cell phone number.
Carry your warranty and all information with you in an organized binder. Read your warranty.
Get a Good Sam book and discount card. Learn what RV Parky and AllStays are. Learn about Pasport America. Get a KOA book - sometimes it's the solution. Learn about BLM lands.
Do not transition driveways without extreme caution. The sewer drains may not clear. Tire stops in parking lots are a similar hazard. Look first before you move.
Most important - Use Liz and make miles with smiles.
