I wrote up a little review about this rack I have on my truck on another website. I thought I'd just post it over here too.
I purchased the Bully dog rack that holds quads, loaded from the side or from the back back in Marck 08. Bullydog ATV was the only company that would customize there truck racks for the customer. I needed my rack to fit my custom Long Travel Rhino that is +8" wide and +6" longer then a stock rhino. They also welded in a Winch mounting plate for my own Warn winch that I already had.
This rack comes already powder coated but he will ship it to you in a raw finish for less money. It was only something like $200.00 less in a raw finish. I could not get it painted for that much so I went with there P.C.
Also the rack comes with ramps for the same price. I have never seen ramps this nice and compact with the weight rating like this before.
My empty rack weighs around 400Lbs so I was told. I loaded it on with a forklift but 2 guys could of done it with out a forklift. The real nice thing about this rack is that it never touches your bed rails or any of your bed sides. It has a box frame design that allows it to distribute the weight over the entire inside of your bed.
They did come out with the model made just for sideXsides like you see in the first post (no center floor and it cost around $400. less). I wanted the full floor so we had a place to stand on while watching the drags, also it gives me the option of loading quads and also I can lock up all my ice chest/gear/bags/gas cans/ect. underneith it with the use of a tailgate handle lock.
As for driving with it on...I have a 12" lift and 38" tires and I fill no differance with it on there loaded then I did with the rhino in the bed. I'm sure there is a differance but I really can't tell. It's kind of like the other guy said...a bed camper weight 3 to 4 times this amount.
Yes you do have to watch the height clearance. I'm 12' 4" to the top of my old rhino cage.
Even with my custom built rack my tires and OEM towing side mirrors still still stick out further then the rack. So I have never had to worry about it hitting a tree or something.
Here's some pics I just took of it sitting in my driveway.
Hope this helps you guys out.
