Recently had a problem when positioning my van on a site where the A-frame was too low to allow fitting the jockey wheel. Had to push the van further back on the slab up against a wire fence to give me just enough height to fit the wheel. This got me thinking about the practicality of the jockey wheel and whether one with a flat plate on the bottom would be more useful. My van is near 22ft and over 2 tonne so the chances of moving it very far by hand is remote. Which also prompted me to think how useful (or not) the handles are on the front of the van.
But finally to a question: are there reasons for or advantages to using a jockey wheel on larger vans? My van usage is on-road, mainly caravan parks with a bit of free camping at easily accessible locations.
As a project, I've been contemplating getting an old jockey wheel, cutting the wheel section off and welding on a flat plate.
