I see internet horse trailer sites that post their price, some that post a wholesale price and some that post the MSRP price.  I didn't pay MSRP for my dually truck and assume correctly or incorrectly that I shouldn't pay that for a trailer?  How far off MSRP do most dealers drop? On one site, a trailer is listed for "wholesale" at $16K and on another site that trailer is listed MSRP for $29K.  Is it then fair to assume that the site with is posted MSRP should be willing to take something in the range of $16-17K for the same trailer?  Or should I assume the dealer will accept something in the middle of the 2? 

Having just purchased a 4 horse slant with 11 ft short wall w/ LQ. Who is to say what the MSRP actually is on a trailer. You can look at identical trailers at different dealers and get 2 different MSRP prices. Then you get 2 different price quotes of what they will sell the trailer for. And if you throw in a trade thats a whole different story. Decide what you want, brand you want, then get a feel for what the average asking price is and go from there. We shopped and looked for over a year. We had a trade-in and no-one seemed to want to give its fair market value at trade. Finally bought  trailer from a dealer 2 states away off this site, sight unseen by us except for email pictures with a trade to dealer for what we were asking that he had never seen except for email pictures. He was willing to deal  on price of trailer and work with us on financeing at the interest rate we wanted. Good luck, take your time, do not let a fast talking salesman talk you into something you are not sure of, in other words do your homework. 

I just purchased a new trailer. It was a custom order, not one off the lot. I figured I had a bit of time that way to dig up valid pricing on it. The deal was a no obligation to buy arrangement, so I ordered it figuring I could do more research.

The price was a bit of sticker shock for me. So, then I spent extensive effort to figure out the "going" price, got ads, both paper and internet. Went back to the dealer and negotiated a very fair price for the unit.

I never did see the trailer in RL. I saw older, entry level versions of it and liked what I saw there. the only disappointment for me was that the deluxe model came with drop downs, but alas they are the smaller size ones, not safe to have a horse's head hanging out:(

Just do your homework and be aggressive with the dealers.
