In this video I show my solution to mounting the Starlink antenna on my Thor Tellaro B Van. I used parts from the home improvement store:

6 foot chain link top rail
Various chain link connectors (see what is available an modify if needed)
6 longer bolts (than came with the connectors)
6 lock washers
Locktite thread locker

Starlink pole mount adapter purchase from Starlink.

I mounted the pole by using some clamp connectors to meet the needs of the install. You may need to see what is available for connectors and repurpose several fittings to get what you need. These are connectors squeeze the pole to secure it. I also purchase lock washers and Locktite to prevent the nuts from loosening while driving. Then I attached the Pole Mount adapter purchased from Starlink. Once parked at the campsite, set it up by running the cable up and out the top of the pole, and connect it to the antenna. #vanlife #RV #starlink
