I got the standard springs, with the Zone UCA's. I left them set from the factory. I'm very happy with the ride on, and off road. My rig is more of a sleeper. Plastic bumpers, stock rims with 295r7018's on them.
It's a pretty standardized industry. Basically, you get what you pay for. White Glove Service costs alot. They also put together group shipments. So if time is not an issue, that could be the way to go. Just make sure to verify their insurance.
