C&C dont know anything about these cages.

What type of cage are you referring to?

Are you talking about C and C style cages? You can buy them in the cage store https://www.guineapigcagesstore.com or you can build your own out of cube grids, cable ties and coroplast (available at walmart, kmart, bed bath and beyond etc. You need 14" square grids with no less than 9 squares across and down per grid). They are very easy to put together. For an RV I think you would want to cable tie the grids together. An even faster option might be to build your cage out of closet wire shelving (16" deep x 48" long available at home depot. You also cable tie it together and it is stronger and faster to assemble than grids because they are only 4 sides to attach vs, several grids) OR you could also cable tie several grids together to make a corral which will accordion fold for storage depending on how much storage space you have. You can make lids out of the closet wire shelving or grids. There are lots of photos in the gallery for different ideas.

If your cage is going to be an odd shape you can also do the bottom tray part with a heavy duty shower curtain instead of the coroplast.
