650 pounds is ridiclulously heavy for a flatbed. Not sure what to say about the spare other than I dont see how you could see a damn thing backing up.
Actually 650lbs is pretty light considering the stock 3rd gen bed weighs over 400lbs alone, and the bumper weighs another 45lbs. For less than 200lbs more than the oem bed/bumper combo I have a full roll cage, and storage space that I can easily access everything I need. I don't have to dig for/unload anything for trail side repairs, and have almost same amount of bed space as an oem bed(absent the room for and aft of the wheel wells).
Granted I could have stopped at a simple flat deck like my first pic w/a roll bar set-up as a lot of f-beds run, and only weighed about 250lbs, which if I had built the truck just for day runs/trailer to campsite and wheel, I would have. However, since I only wheel when camping and don't trailer my junk, I need to have room to carry everything needed for trail repairs as well as the gear I carry that makes camping enjoyable, i.e. more than an ice chest and a sleeping bag.
I haven't had an issue backing up on the trail, it isn't any harder w/the spare tire back there than on my '90 w/a shell. I did have plans to add a back-up camera, but haven't found that I really need one.
