Issue with brand new truck. Advice on how to proceed?

Ok folks, here's the deal. On 11/25/2014 I bought a brand new 2014 Ram Express. I went into the dealership the Saturday before (11/22/14) and they didn't have anything on the lot that I wanted, and there wasn't one in the state that I could find that I wanted, so they dealer traded for one that had everything I wanted from Oklahoma.

I originally wanted to make a purchase that Saturday I went into the dealer, it was between a '14 F150 I found and liked at a lot across the street and the eventual Ram I ended up buying. The reason I bought the Ram was because they threw in a window tint and a set of steps at dealer cost and let me take one of their new trucks from the lot for the weekend if I agreed to wait till the few days on take delivery on Monday, and HERE is where it gets interesting...

I contacted the salesman just before 10AM Monday and checked in to see if they had made contact with the other dealer, he responded right away and said that they had already spoke around 9:30. Just before 11AM he replied again letting me know that the trade was worked out and they were just waiting on paperwork.

At 2pm he contacted me and said it would be better to take delivery early morning Tuesday, to which I said I wasn't interested in. He then said that if I wanted it that bad that he would stay till around 9PM, when the driver would be back and I could come in and pick it up.

At 6PM I sent a message asking him how the trip was going and got no reply, figuring he was busy and didn't have time to answer back I went up there at the agreed 9PM to find a locked lot gate and a ghost town for a dealership.

The following morning, and throughout the day we messaged back and forth, and finally at 4PM he told me the truck was there, so I went and picked it up, solely from them because there were zero other Rams within the area that I was interested in and didn't want to start all over again at another dealer.

Skip a few days and I notice a funny looking spot on the front drivers side of the hood, looking at it closer I could see sand marks that are clearly UNDER the clear coat. Thinking that this would have been a factory fubar, since it's a BRAND NEW truck, I took it into a different dealer since I was done dealing with the purchasing dealer.

The other dealer took some pictures and submitted a warranty repair request, and I was required to get a written estimate for cost of repair (Which seems odd to me). I took it back to the purchasing dealers body shop, with out informing the sales team, and they told me that the repair was definitely done POST factory as there was a visible tape line under the hood that does not exist from the factory. After the body shop looked it over and wrote the estimate, I went and talked to the sales manager about the issue. I asked if they had any knowledge of this and he denied knowing of any repair work done.

I heard back today from the other dealer that he had found some info about the truck. He said that the purchasing dealer got the truck on dealer trade, which I obviously already knew, and that the repair work was done by the purchasing dealer.
Now, I haven't been able to speak with this dealer that relayed this info to me as it was a voicemail message.

How should I proceed with this? The purchasing dealer has already denied taking part in any repair work, and their own body shop said they didn't show any record of work done, but says it was definitely done after the factory. I'm sort of at a loss as to how there can be paint repair done and not mentioned to anyone. I didn't want to purchase a vehicle with any repair work of this sort, other wise I would have purchased a year or two old truck used.

So... sorry about the long winded post, but any ideas?
