Mounting an Apartment Style Refrigerator in RV

[Jkountz]

Well I scored a heck of a deal on a nice stainless steel 4.3 cu ft fridge for the RV. I still have to remove the original one but now Im wondering how I can secure the new one so it doesnt slide or fall out during transit. I cant get to the underside of the compartment because thats where my converter and all the breakers are mounted. I didnt really want to go the bungee cord route either.
Any ideas for this? Im a little leary of driving any screws or anything into the side although it might be ok to do that, not sure.

I bolted L-brackets to the fridge and the floor, worked great.
