Ground clearance and grip
Inspect the vehicle's low points, steps, underbody tanks and departure angle. Suitable tyres can make a substantial difference. Even a four-wheel-drive vehicle may become stuck on soft ground, and access restrictions must always be respected.
Transmission and servicing
Ask for records covering differentials, shafts and any transfer case. Check the engagement of the system according to the manufacturer's instructions. A specialist inspection can be useful when the history is incomplete.
Weight and licence entitlement
Off-road accessories, larger tyres and extra batteries can reduce the remaining payload. Confirm maximum permitted mass, load limits and your driving entitlement. A heavily equipped vehicle may be less practical for everyday camping than expected.
Choosing for real journeys
If nearly every trip uses normal roads, assess fuel use, tyres, noise and repair costs alongside traction. For remote journeys, reliability and access to water and power may be just as important as the drivetrain.
A more complex drivetrain
Four-wheel drive introduces components that need specialist knowledge and maintenance. Compare the costs of differentials, tyres, shafts and servicing against an ordinary campervan. On long road journeys, fuel consumption, engine noise and comfortable seating may matter far more than traction on the occasional loose track. Work backwards from the routes you truly intend to drive.
Independent travel is about systems
A vehicle parked away from a serviced campsite still needs safe water, power, heating and waste arrangements. All-wheel drive does not improve those systems. Check tank protection, battery condition, heater access and the availability of repair parts. A clearly documented and well maintained installation may prove more valuable than a heavily modified vehicle with difficult-to-service equipment.
Road test and inspection
Drive the motorhome on normal roads first, paying attention to vibration, braking, steering and wind noise. Have the seller demonstrate the drivetrain controls according to the manual. Inspect corrosion around the underside, particularly on vehicles frequently used with road salt or wet conditions. Do not attempt risky off-road manoeuvres to test a vehicle that is unfamiliar to you.
