Thanks for the feedback.
The original jump seat arrangement was actually pretty practical. In the later years of hunting in this vehicle, the roll bar went on and one jump seat was mounted on square tubes, facing foreword. A storage box went under the rear seat. With the top off that works great.
With the top on, that arrangement makes getting in the back seat is impossible from the back of the vehicle. Only being accessible by folding down a front seat is awkward at best.
Seatbelts? Never.
O.G. perspective on rolling vehicles....We had some hard and fast rules. Safe careful driving in the hills .... always. Never drive on a side hill, always go straight up or straight down, this is huge. Never drive fast in the hills. Never install a lift kit. Giant tires were useless for our purposes. Do not install a super powerful engine. Choose any off road path carefully before you drive it. If you observe those simple rules you will never roll a vehicle.
I know that is boring but it works. My perspective is from a ranching and hunting, not a purely recreational perspective. That perspective is unusual here, I understand that.
