Overall a very good tent. Setup is easy, even for one person. About 15 minutes the first time, much less on subsequent setups. Tie downs are great and the installed finish-protectors on the straps work fine to protect the vehicle paint. The only reason this is not a 5 star product: The rain fly seems to fit too tightly to the tent. This effectively seals the ventilation side mesh and blocks most, if not all the air flow with the rain fly fully strapped in place. I'll keep attempting to tweak the rain fly to see if I can loosen it up a bit. Will update the review as needed. I've not experienced rain yet, so I have no comment on the tent's water worthiness.
Also, one tent pole had failure of the inner bungee cord on 2nd take-down. The pole is still usable, but now is mildly inconvenient. Warranty service was submitted to Napier, so we'll see how they respond.
One enhancement that would be great if they could engineer it: Since most trucks have a cargo light in the center-high brake light assembly, it would be nice if Napier could put a mesh opening (with a roll-up/down cover?) that could align (approximately) with the cargo light. That way, the user could turn on the vehicle cargo light and use as an interior tent light.

I love this tent. Being off the ground and having the hard sides of the truck bed makes my wife feel a little more safe than a tent on the ground. I use the tent with my roll up tonneau cover on my 2011 Silverado 1500. I roll the cover up and put the tent on the bed of the truck (the tent will fit over the rolled up cover). It fits just fine with the cover rolled up. When I go to move to a new campsite I deflate my air mattress, leave my sleeping bags inside the tent, collapse the tent in the bed of the truck, unroll the cover, and drive off! It takes about 4 minutes to take the tent down and 10 minutes to put it back up. I have attached pictures of the process. I am also still able to put a cooler in the bed of the truck along with some other things. Make sure to have a step ladder to help yourself get in and out of the tent.

I used this tent on a camping trip with my girlfriend to glacier national park. Before we left we set it up in the driveway once, and after that it was easy to do. We set it up four times on the trip and I think we can do it together in 5-10 minutes now. Our preferred method was to lay it out on top of the truck bed and then put the poles in, contrary to the tip in the instructions. The instructions are sewn into the bag and it gives a specific order for insertion of poles. We followed this order and did not have any poles break. A few tips of my own; don't loosen the straps to take the tent down, just stretch the elastic straps. That way they are the correct length for your specific pickup the next time you install it. The easiest part to screw up is the pole which forms an arch over the door. It needs to be assembled exactly as shown in the image for the product listing. The fabric goes inside of the tailgate support cables, and the pole goes to the outside of them. Otherwise it will get all stretched out funny in the front. You will realize if you make the mistake. Be careful when inserting the poles, and don't pull too hard on the shock cords, some people don't realize that all fiberglass tent poles can be easily broken if handled incorrectly and the shock cords will pull right out if you try remove the poles by simply pulling on one end. They must be pushed through to assemble and pushed back out to disassemble. The tent fits over the sides of the bed so the bed rails create somewhat of a shelf on each side that is nice for putting things you want to find at night. I bought a $7 lantern at walmart that was a perfect size for the tent, and the tent comes with a carabiner in the center for hanging just such a thing. I brought along a moving blanket and layed it out on the floor to protect the floor and our knees, it was the perfect size for it. I used my big cooler as a step for getting in and out with an outdoor rug in front of it for shoes. We stayed in two cots which worked out nicely, but they make air matresses for truck beds which would be nice to try.

I purposely waited until we had a chance to use the tent before writing this review. We used this tent in an F150 with a BestTop roll up style bed cover. From the earlier reviews we did a practice run putting the tent up before going on our trip. The first time was slightly cumbersome, but not bad. Once we had it, it was easy the next several times we put it up and down. Quality was good and nothing broke or malfunctioned until the very last day. The string which held the green pole together broke the final time we disassembled the tent for the ride home. I'm going to try to get a replacement and will update this with the results. I'll I felt as if the bed of the truck was adequately protected.

The experience of using the tent was great. We camped in Colorado with weather down to 40F and up to 85F. It rained multiple times during our trip. The tent never leaked. It did have condensate, but it did not leak. The tent has a net at the top. We used this to hold our iPad and watch movies at night which was fun. The interesting part of our trip was we had to use our truck every day during the trip. I built a platform for a bed in the truck which had to be removed before removing the tent. We didn't want to disassemble the entire setup each day so I simply removed the poles, unhooked the straps and folded the tent into the back of the truck then rolled the bed cover over it all. This worked great. It also allowed me to take down and put up the tent several times in this one trip. I became pretty quick at putting it up. With help it could pop right up in 10 minutes. All of the clips and straps held strong through all of this up and down with the tent. As mentioned before, the only issue with any hardware was the string on the green pole.

Even with that one issue I think this tent is of very good quality and worthy of a high ranking. It handled the weather nicely, was simple to set up and take down and had as much room as one could possibly expect in a tent for a short bed truck. I'm happy with the purchase.

One thing you'll need to get used to is everyone asking about the tent. We had a lot of people stop by and look at the setup.

UPDATE:
Napier customer service proved to be fantastic. They sent a replacement green pole quickly. We are still very happy with this purchase.

Everything was going great until I tried to put the rain fly on. The green pole immediately split in half. I have placed a call to Napier customer service today, July 2, 2016, so I will keep this review updated as to the quality of Napier's customer service.
Update: Napier sent me a new pole which arrived about a week later. The pole was different, and obviously used but it works so I guess I cant complain. The tent itself is great. All fabric is sewed well and fits tightly onto my truck. I'm looking forward to many trips with it.
