Buy for gravel and wind, not for rock
South Dakota rewards range and payload over articulation. The roads are gravel, prairie two-track and narrow pavement, with almost 600,000 acres of Buffalo Gap grassland and more than 3,800 miles of Black Hills road and trail to cover. What it punishes is size in one specific way: the tunnels. The narrowest published in Custer State Park is 8 feet 0 inches wide by 9 feet 9 inches high, and the narrowest on the Peter Norbeck byway is 10 feet. Ask a dealer for loaded height and width, not just the brochure figure.
Buying a finished vehicle trades money for time. Someone else has already made the thousand decisions, and you can be traveling this season. A dealer who knows these vehicles can also tell you what a used one has been through.

How to buy a finished vehicle
The questions are the same whether it is new or used.
01Ask for weights: empty, loaded, and the gross rating. Overweight expedition vehicles are common.
02Ask for the build documentation: wiring diagrams, component manuals and service history.
03On a used vehicle, have the chassis and the house inspected independently before you buy.
04Ask who services what after the sale, and where.
05Drive it, on dirt if they will let you.
What to have ready before you ask
Know the trip before you choose the truck.
01How many people travel, and for how long
02Where you want to take it, and what you need to park it
03New, used, or either
04A budget range, and whether you have a trade
05When you want to be on the road
Questions people ask
Is it cheaper to buy a finished vehicle or build one?
A used, finished vehicle is often the least expensive way into a capable rig, because builds rarely return what was spent on them. A new custom build costs the most and fits you best. Building it yourself costs the least money and the most time.
What should I check on a used build?
Weight against rating, water damage and leaks, the age and type of the batteries, heater and appliance service history, and the condition of the frame and suspension. Then have a mechanic check the vehicle underneath the camper.
Can I finance an expedition vehicle?
Often, through RV or specialty lenders, depending on the vehicle and how it is titled. Dealers who sell these regularly know which lenders will.
How high is South Dakota?
From Chamberlain at 1,407 feet to Black Elk Peak at 7,242.
Altitude decides what your engine, your brakes and your lungs have to work with, and how late in the year the passes open.
