I do suggest performing a thorough pre delivery service & walk around with a knowledgeable person from your dealer. We had the salesman AND a technician do ours.
Take notes, take pictures, ask questions, and operate EVERYTHING. That includes all faucets (including inside & outside), the TV & stereo (inside & outside), all the light switches, all kitchen appliances, BOTH A/Cs, operate the slides a few times each, and make sure your 3 LP tanks are full.
I ended up labeling the switches with a label maker as there are so many.
Columbus makes a beautiful rig, we really liked the 365RL, but it was a bit too much for my 2500.
Once you get finished with the PDS, go enjoy it!
