Argosy 20 Part???
I am not certain how the device may have been used with a travel trailer, but we had a set of 4 of the bases pictured that we utilized with "pole" stabilizers that attached to the side of our 1969 SunWay pickup camper at each corner. These were lighter than the jacks utilized to remove the camper from the truck, and were designed to limit the side to side movement of the camper when setup in camp.
If I still had my bases, I would be using them as flag stands when attending a rally. An anchoring device would likely be necessary, but the bases that we had with the SunWay were the size of the flagpoles that I carry for rallys.
