I know some time has past and you may have already sorted this out, but I'll show what we do with our table and chairs.
Ours came from the factory with the table not mounted to the floor. Sunline was out of business by the time we got the trailer, so we could not ask them how they wanted to do this securing for travel.
Here is what we do. The wife really likes that the table is not mounted to the floor as she slides the table on the carpet standing up to the end of the slide room when not in use to create more room in the camper. Then we slide the table back to eating position when we need to use it etc.
It came with 4 chairs, but we now only use 2 of them since 98% of the time, it is just the two of us. The other 2% of the time, we bring the other 2 chairs with us.

We lay over the table down and to the front of the slide to travel. The chairs are stacked in such a way, the seat fabric isolates the wood to wood touching. We tried this many ways, and this is the final setup we came up with. It has worked since 2007 and over 45,000 miles with no damage. We really like it


If we carry 4 chairs, it looks like this.

I will say this, the table and chairs is slight forward of the TT front axle. It is not way behind the axles. I also have shocks and a Trail Aire rubber equalizer. The suspensions upgrades really help tame down the road bounce.
I'm not sure we could do this if the table was at the back of the camper. The bounce is more magnified back there. I can tell by the swivel rockers that move some on bad roads.
Hope this helps give you some ideas to build off of.
