We went with a clear acrylic urethane, no stain.
We didn't want to change the cover so we stayed away from oil based.

Just FYI, I believe the slab we picked up from HomeDepot stated that it needed to be sealed within 24 hours of unwrapping.

I wish the kitchen in my house looked this nice!

Me too!

Thanks to everyone for their input! And agree that @wallsonwheels has a very posh van kitchen, super sharp interior!

It sounds like sealing is the way to go, given the temperature and humidity cycling in the van. I appreciate a good patina as much as anyone, but I would prefer not to have to replace this countertop if it starts to split, etc.

@wallsonwheels was there a particular finish (semi-gloss etc) for the acrylic urethane you used, or do you remember the specific product? I would prefer a less shiny countertop (yours looks great in the picture). @Swamplizard a two part epoxy is very nice, but probably too much hassle (for me) to put on. Hardness is less important to me, I just don't want it to split and warp.

Thanks all!

Thanks, this is what we used:

This is only our first season out, but so far so good, it has held up very well for us.
Spar urethane was the other way I was thinking of going (bulletproof) but that would have changed the color a bit.
The wood is clear birch from HD or Lowes.
