Awhile back I had seen an ad for letting you remove your wing tie down bolts and installing a tool in that hole that would let you jack the wing up to change a tire anyone know about a tool like that?
Thanks

Be very careful using jack pads - especially with one wing and no tail stand. They have a nasty proclivity to slip off the jack and then you have a big hole in your wing. You might consider placing a piece of 2X6 wood with foam or carpet between the tie down bolt hole and jack instead.
I would suggest you go to Vans site and read how the factory recommends jacking your RV. Your statement contradicts this and many of us who have followed Vans recommended practices for years. The few problems that I am aware of where pure negligence.
You couldn't knock my RV off the jacks if you tried.
By the way, for the OP, yes, you can buy an expensive insert, or you can do like most of us; grind down the head of a grade5 or grade8 bolt and use a proper jack adaptor with a dished out receiver. By the way, Vans used to supply a plastic insert, yes plastic. I used it for years before making my own bolts.
I thought of carriage bolts initially but the ones in our local hardware store looked pretty crude & maybe brittle.
Cleveland tool makes a tie down that I use as a jack point. I never take them out.

I just bought some large steel pipe caps, drilled them in the center, and inserted a grade 8 bolt and put a washer and nut to hold it in place to capture the hydraulic ram from the jack.
Easy project at minimal cost and they have performed just fine for jacking up the airplane.
For best results and safety, you need to angle the jack outward at the base. The angle at the jackpoint gets surprisingly large and scary looking as you raise the wing high enough to get the tire off the ground.
