I've used Dave Smith before and been very pleased with them. Unfortunately I ordered from them this time before learning about the Big Bob special at Dishman. Oh well, not much of a price difference but I'd like to have purchased from someone supporting the TDR.
I did call Butch at Dishman just to be sure I shouldn't cancel my order and start over, difference was only $500 bucks or so.
The comment above about selling your rig before you go to Dishman because they can't afford to pay you for your trade-in may not be entirely accurate. They offered average trade-in value on my '02 Durango without seeing the thing ($20,000), Dave Smith won't talk about trade in value until they see it (they said it would be $17,500 or higher depending on condition).
My new truck is in Idaho today, picking it up Saturday - assuming they give me a fair trade on the Durango, otherwise I'll be stopping in to see Butch on Saturday.
