What I have found is that anything you want repaired before taking delivery of the rig is attended to immediately. After you have taken delivery and the money is in their pockets it takes 3 and 4 weeks in some cases for the simplest repairs. The excuse after the sale is that they have to contact the manufacturer's warranty department and await an approval before completing repairs.
It would be wise to make a checklist of items before accepting delivery. A pre delivery inspection of all operating components, such as running the slides in and out several times and check that they are sealing properly, run the awning out and make sure nothing is binding and all looks good, have them turn the fridge on before your arrival to make sure its cooling, have water hooked up to rig and run in every sink and shower watching for water leaks under cabinets where drains are located, etc. The most common problem with new rigs is water leaks and loose electrical wiring, or things not wired, such as antennas and etc.
This may sound like a lot to ask of the dealer but smart buyers do this all the time. I was given a 4 hr slot for a PDI and still missed a few things that I forgot to check. You'll be glad you did if you follow this advice. There's nothing worse than gettin all excited about your first campout only to find multiple problems and having to bring your rig back and wait weeks for them to even take a look at it.
Some dealer will let you stay overnight in the rig on their premises to check everything out !
If they balk on a lengthy PDI, threaten to walk. They want the sale and will most likely be more than willing to take the amount of time you request.
