That tire is held on with a cloth strap, which the moment it gets wet will loosen a little and you will get the mild result of the time bouncing up and down a little on the roof.
Bouncing up and down is the least of the worries. If the straps loosen that tire might join the occupants in the front cab coming thru the windshield. I would fabricate a mount, in front on the aftermarket and very cool bumper or something in the rear, perhaps incorporating the truck's reciever with an extension somehow.
If my math is correct, 29 Northwood employees on the roof at one time with an average of 150 pounds each is a total of 4900 roof pounds. That is a lot!
Roof tire issue aside, the bumper, tires and wheels are great!

Ditto - that is really nice! The tire might even help block/break branches that might hit the AC and other stuff on the roof. Maybe cables of some sort might take that abuse better than nylon if it happened much.
I was not aware that the nylon straps had any give when wet. I have checked that tire more times than i can count and it has not budged. Not saying you are wrong. I most certainly do not want that thing comming off. There are no wear marks or any proof of movement that i can see. Of corse this being my first trip out with the supers this is the first time with that tire. However i have had another tire up there for quite some time. Is there any strap you would recommend for this situation.
They do, I use them for securing loads on my front cargo rack and have to retighten them after they have been given a good soaking by rain while traveling.
The straps will work fine, but its best to know their behavior so to not get caught unawares.
Traditionally folks put roof pods and what not up on their camper's tops that likely can weight when loaded close to that tire, however, they're usually mounted on roof racks or other structures lifting them up off the actual roof itself so that any movement is transferred to the outside wall structure where the roof racks are attached vs onto the rubber-like material of the roof itself and the plywood (Or chip board, depending on MFG) underneath.

I agree with the others that nylon webbing straps do loosen when wet. I have experienced it many times with my motorcycles/atv's and other cargo as well. Buckle straps loosen far worse than ratchet straps because the buckles slip.
Also, nylon webbing straps deteriorate in direct sunlight, which that strap on the roof will get plenty of.
The tire should stay with the truck at all times, whether the camper is on or off. With the tire on the camper, you have no spare when the camper is not on the truck.
I would mount the tire to a front bumper/hitch tire rack, that can also be used with or without the front hitch cargo rack. That way the tire stays with the truck at all times, whether the cargo rack is on or off the truck and whether the camper is on or off the truck.
Well had a great time and zero issues. The snow has been spotty to say the least this year but we got lucky. We were a little worried about the mud. I have to admit I have been a little unhappy with my 19.5's because of the ride and the way they have handled the ruts in the roads. But after having the camper on with them I have to say wow what a difference. The rig handles much better. I guess I will have to put more weight in the back when the camper is not on.
Whe went to Portage Lake camp ground in waterloo state recreation area. To our suprise there were actually 5 other campers there. The kids buit a snow man and a good time was had by all.
I think I will move that tire to just behind my carrier. Not only because I trust and respect the opinions here but I also want to add some solar panels in that location. Does anyone know of a manufacturer that makes a mount that I can just bolt to the 2" tube that my cage is hooked to.

Southwest Wheel sells a bolt-on spare tire carrier made for mounting to utility trailers that you could likely use to bolt onto your hitch rack. Go to the trailer parts section of their website and you will find it in there. I don't know how much it costs.
