With help from those here and much research I pulled the trigger yesterday and placed a custom order for a '20 Laramie Crew 4x4 EcoDiesel here in SoCal (Lake Elsinore). Dealer was a Costco referral that was more accommodating than most others to placing an order at a fair discount. Final tab $55,405...$7,000 under MSRP, $2,000 under invoice, roughly halfway between FFP and EP pricing. All before any rebates/incentives at delivery. Minimum doc fee of $85 and nothing else. Surely not the best deal here but fair for SoCal. I reached out to many local dealers and even a couple in other states to get competing bids and was either blown off or told to take the Lake Elsinore offer as they wouldn't/couldn't beat it on factory order.
Buying off a lot was not in the cards as my build was not "mainstream" enough for any dealer on the west coast to order for stock: EcoDiesel and 3.92 gears, 33 gallon fuel tank, Laramie Level 1, air suspension, pano sunroof, Off-Road group, 18" wheels and LT tires (no 20's for me), trailer-tow group, brown/beige bucket seats, 8.4" screen w/nav, rubber mats and underseat storage. All covered in beautiful Delmonico Red...with no wasted money on sport, night, chrome or wheel packages that do nothing but just jack up the price. Not everyone's cup of tea but perfectly suited for frequent long trips towing our travel trailer in comfort and style and off road exploring when we get there.
Now the waiting begins...
