Are you going to move the camper at all? If so, I think getting your TT back in the exact same spot to line up with the permanently mounted feet on the deck will be really tough. If you're looking to mount the feet without moving the camper, which is what you seem to be looking to do, consider this...
rather than looking for some toe stubbers that will always remain on your decking, try an anchored nut that flush mounts to the decking. You can find them to fit concrete or wood and also in the appropriate width of bolt for the guide holes on the feet and the depth of the nut into decking.
You'll be able to use the feet you currently have and return them to the camper side when you'd like to roll up. I'm pretty sure they even make these where the bolt returns to the anchor, flushed, so that your nut doesn't fill up with debris when not in use.
A few things you'll want to consider if you're going to go this directions...
Get brass or stainless hardware so it holds up to the weather for years to come.
Be careful and do your measuring and calculations twice and drilling once as you're not going to want extra 'error holes', especially in concrete.
Just some food for thought to avoid the search for new feet.
Use the appropriate method to set your anchors, you don't want the threads to get compromised on installation.
