All good responses.....you definitely want to acclimate them to the idea by spending a night or more in camper. I would bring the crate for the one you described. Hopefully, you can fit it in. We have an Australian shepherd & a Sheltie that do well hanging out. We always pull shades, turn on AC or the central fan and radio for them. Both get a lot of walking exercise when camping, so we make sure they are tired when we leave. When camping we do carry bark collars with us. Sometimes they need to wear them if camped near a yappy dog. This is while we are there and out at the campsite. It's their clue that they are not to respond to other dog stimuli! Good luck and have fun!
