Buy for the road limits, not the brochure
Washington posts its limits in feet. Nothing over 22 feet long or 8 feet wide inside the North Cascades boundary on Cascade River Road. No trailers on Road 5400 to Harts Pass and motor homes strongly discouraged. Forest Road 99 called unsuitable for trailers. Obstruction Point and Deer Park unsuitable for RVs.
A large expedition truck will still reach most national forest campgrounds and the whole Yakima River Canyon. It will not reach Cascade Pass or Harts Pass. Ask a dealer which of these roads a vehicle has actually been driven on.
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 Washington?
From Long Beach at 20 feet to Mount Rainier at 14,411.
Altitude decides what your engine, your brakes and your lungs have to work with, and how late in the year the passes open.
