I wasted 2 1/2 months with my local AS dealer trying to get a spare wheel & tire for my 99 Safari. First time they got the right wheel and wrong tire, 2nd time they got the right tire, but wrong brand and wrong wheel. These were ordered via Airstream.
Both times they got the right Airstream PN - but wrong item.
A simple email and phonecall to InlandRV delivered the correct wheel to my front door a week later. Cost was about the same. This was also ordered via Airstream and shipped direct to me from Titan.
For older trailers, InlandRV should be the first place to look as they understand the safety issues too.
Kudos to Andy & his team
