I think I have that same tent. Except for a 5'-8" bed. I ordered it on Amazon, 4 or 5 years ago.
We used it once. It was late June, we went pretty backcountry here in Montana, and got snowed on so hard and so much, we ended up leaving middle of the night. FWIW, the tent did fine, but no way did we want to wake up and deal with 8 to 12 inches of wet, new snow. As it was, there was 5 or 6" when we packed up and left about 3 am. I actually just folded the tent poles down and threw everything on top of it until we got home instead of trying to take it down and box the tent up in that kind of snow. IDK how much it snowed that night, glad we got out of there.
The tent has been used one other time, by my wife's brother. I never heard how it worked for him. He has a 2008 longbed Silverado. I am assuming it worked OK since I didn't hear otherwise.
I think it is a good tent. I think truck-bed tents can chafe or scratch the paint a little. But I am a contractor, who uses my truck daily as a contractor - it is all but impossible to keep my truck as nice as I'd like. Not that I want extra scratches, etc, just that is something to consider with a truck bed tent. Just look at how the straps cross the bed/paint.
We may use it again, just not sure when. Life, kids, work, etc (10 people live in my house, sometimes 11), make finding time to do anything like this with my wife... difficult. I have considered taking a solo trip down through southern Utah and northern Arizona. I did this in 2014, except on a motorcyle, loaded to the gills. Camped every night, usually hadn't even picked or found my camp site until about dark. I was alone (even though I was accused of not being alone, lol), and it was a hell of a trip. 6 days, 3500 miles, plus lots of miles hiked on foot in the canyonlands type terrain of southern Utah. Started the trip in very late August in 95 degree temps, came home in early Sept to snowing (again, I was on a motorcycle) the last 60 miles home in Montana. That is Montana weather for you!
I have strongly considered doing this again, but this time in my truck (currently 23 AT4X) and using my truck tent each night instead of unpacking/repacking a loaded motorcycle (was not a bagger bike, so I had to get creative). Would be nice not to have to tear the tent down daily - would like to be able to just lay the tent flat with the poles taken out, but probably not the best idea. Plus now I have a tonneau cover, so that is likely in the way. I'd have to remove that first. Hell, I could just shimmy in under the tonneau cover as my "tent" - have considered it!
But I digressed. I think the tent you have shown in the pic would be fine. I seem to remember I paid about $200 for mine, a little foggy on the exact price but somewhere in that range.
