If you're under the weight limit and able to climb the ladder and walk on the roof of your RV or motorhome, this might be a good solution for you. Instead of attaching a flagpole to your ladder, fix a small aluminum mount at the top, and slot your starlink into it.

Link to mount from Axia Alloys, don't forget to buy the clamps also:
