Bring your local dealer for the same brand a written, out the door quote from the out of town dealer. Telling a dealer you can get it cheaper doesn't work, you have to prove it if you want to buy local and get the best buy you can. Factor in freight because the further away from the factory a dealer is, the more they have in freight costs.
Keep in mind that RV dealers are not required to do warranty work on units they don't sell so if you decide to buy out of your local area, don't go back online bashing a dealer that didn't sell you a unit and won't take on your warranty headaches.
I understand your point about overhead, but there are huge differences in overhead that we will never know. A dealer in a metro area likely has much higher real estate costs and property tax's than one located in a small, rural community or in a field, even if both have first rate buildings and service departments.
I always support local business if I can but if in the end the difference is 10-15k I would have a hard time paying that to.
