How does having the camper on the back affect the driving?
To a considerable extent this depends on how well the camper and pickup are matched (See matching the camper to the pickup) but obviously the combination will be heavier and will have a higher centre of gravity than the pickup alone. This will inevitably be felt in the way the combination drives, with an impact on acceleration and braking times and with a tendency to roll on roundabouts and tight corners. This tendency can be limited, if necessary, by the fitting of assisted suspension. Careful packing, as low and as far forward as possible, can help to minimise the effect. A demountable unit that is properly fitted and secured will not be able to move about in the pickup bed.
