First of all, you're going to have to get there. You might just take a look at several "traveling" threads, which may make the trip go well/better.

I'm not sure if I'd call what you're going to do "camping" given it's going to be in a Cabin. Does it have running water, electricity, hard to advise you without knowing things like that. Those topics related to supplies taken.
What we can discuss are two things, Potty and Movement Control.
Are you going to take Potty Pads ?
If so, I'd suggest that you get a Plastic Bag and place a piece of Fecal Material in it, and, blot a deposit of Urine with a Paper Towel, where you can "scent" the area (Potty Pad) in which you wish potty to take place. If you intend to keep him inside, like overnight, this will give him a reference to where to Potty.
You may wish to leave him outside unattended.
There may be other things you want to do beside keep an eye on your little one full time. So, I'd suggest a 25' Retractable Leash/Reel, with a short piece of Rope, where you could tie the Reel to a Tree or your Vehicle, where he could have limited "roaming" ability outside. If 25' is insufficient, you might buy a longer piece of Nylon Rope and a Snap Hook, and make a long Leash yourself. I hope you have a good Harness for him.
I don't think you're going to have much of a Barking problem.
Given his age, I think he probably will "hide" psychologically in that environment rather than "announce". An older animals protective instinct would/may cause barking, I don't think he's there yet.
I'm not sure what else to talk about, you have any specific questions ?
