I'm sure it will depend on the dealer, (Not a discussion of Camping World here). My experience was decent with Four Seasons in 2016. PDI was adequate, obviously you're not going to test toilets and towing etc. in the parking lot. Look for obvious faults, but know that most problems don't show till you put the systems under load which will happen miles away from the dealership. Plan to be brow beaten for additional warranties and service offers. More profit for the dealership. Have "No thank you" printed on your forehead. If you are still in the dealing stage, don't be afraid to ask them for options such as Fantastic Fans etc. Many times they will get stuck on a price, but will toss in stuff to close the deal. If you find major faults with the Rig, DO NOT CLOSE THE DEAL! Read these pages. You will find many stories of people buying rigs and then not being able to use them for weeks and months because of major repairs. Finally, as others have said, keep it a business deal. Do not let your emotions get involved. If everything isn't right, WALK. There will be a better day.
