I bought new 1 1/2 years ago. I took basically no problems to them (no walk through) in return for a lower price. The warranty was virtually useless as well, since it would involve hours of driving to the nearest dealer, vs just fixing it yourself.
I've never gotten, or sought, much warranty consideration, my whole life, other than ordering something and getting the wrong item exchanged for the right item, or a broken item arriving. Warranties seem to run out before the normal life expectancy of anything, and are fraught with exclusions, so I always make price a consideration over warranty. Like you, I always offer the closest dealer a fair offer, based on what the market will sell it for. $1200 seems like too much of a difference.
My experience is that warranty work on an RV is hard to redeem, since you're traveling, and it would disrupt your vacation to take it in hours away, etc. I also bought a new trailer once, had it delivered, arrived with broken window. I simply asked for a replacement window that I would replace myself, they never did anything. Same with my recent motorhome. Cracked fridge vent from delivery trip hitting a branch. Nope, that's not covered! Easy to fix, so I cut my losses, despite showing them photos of the damage.
This forum is a very broad swath of good people, and I have seen many, many opinions that would counter what I just said. They would have the necessary patience and skills to pursue their legal rights and maybe get things done that I would just 'write off' and fix myself. So, it's really up to you.
Lower purchase price= lower sales tax and lower insurance cost, and lower property tax if you're unlucky enough to be taxed annually on the RV. I say learn all you can about maintenance and the various systems onboard, and take it to the closest dealer for catastrophic warranty work (unlikely).
Load all the component manuals onto one of your electronic devices, and you'll be way ahead, either way, since you will be able to troubleshoot many problems that some might take to the dealer.
