My buddy told me to "Never put a camper in a truck with a bed liner" I couldn't get a reason from him and I don't see any reason why not. Then I was reading on Torklift that if you use a bedliner it will void your tiedown guarantee. The only reason i could see is that it makes the bed a little more slippery but not much more.
Do you know any reason for this? My truck has a bed liner and I haven't had a problem yet but don't want to have one.
