83 Army Corps of Engineers, 8 National Park Service, 5 Forest Service, 2 refuge. 92 can be booked ahead, and the total is the highest of any Great Plains state in this build
NOAA puts it at less than 20 inches in the west and more than 50 in the southeast, which is the whole planning problem in one line
Buy for lakes and forest roads, not for passes
Oklahoma is a state where a modest vehicle goes almost everywhere. The byways are numbered highway, the federal camping is overwhelmingly on Corps of Engineers lakes with made access, and there is no altitude to plan around between 289 feet and 4,973 feet.
A big expedition truck buys comfort through heat, humidity and ice, and the range to cross the panhandle where Guymon and Boise City are the resupply. It costs you the narrow forest roads in the Ouachita and the state park campsites, which are booked online and sized for ordinary rigs.
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 Oklahoma?
From Broken Bow at 468 feet to Black Mesa at 4,973.
Altitude decides what your engine, your brakes and your lungs have to work with, and how late in the year the passes open.
