If you have "standard" skewer fork mounts, I carry my Trek's on the dining table inside the camper.
I mount these forks to a 1x4, clear off the cushions in the u-shaped dinette, and then put a 1x4 on each side. I've also screwed in 2 eye hooks opposite the fork mounts, and am able to bungee cord my rear wheel to the eye hooks, while the front fork goes into these mounts:
