This is an update to my initial review of this pickup rack that I did in April 2015. I initially installed the rack on a Ford F250. The racks are fully adjustable and can be installed on most any compact, midsize, or full size pickup. I installed the racks by drilling holes in my pickup bed rails, but they could be installed with pickup camper clamps. Personally, I felt more comfortable making a permanent installation using nuts and bolts.Installation is fairly straightforward and can be accomplished by most anyone with a drill and basic hand tools Actual installation time was about 2.5 hours. The paint that comes on the racks is, in my opinion, of poor quality and I suggest that you paint the racks with a good grade of paint prior to installation on your vehicle. I did paint mine prior to installation, but several months after I put them on, rust stains started appearing at points where parts joined on the individual bars. I am attaching pictures,I recently decided to trade my F250 on a new vehicle and as a result I removed the racks. Upon removal, I discovered what caused the rust stains on the joints. When I installed the racks, they appeared to have enough points for water to drain from inside the uprights. However, none of the base plates actually had drain holes and as a result, the upright sections of the racks filled with rain water which would leak at the joints and would cause the rust stains. The solution to this problem is to drill a 1/8 inch hole through the bottom of each base plate into the upright bars. This will allow rain, snow, and other condensation to drain and will prevent the rust stained joints. If you drill the holes prior to repainting the racks, you will prevent rust from forming around the drain holes.I have re-installed the racks on a Ford F150 and they fit both the F150 and F250 equally well. Since the racks were rust stained around the joints, I repainted them prior to re-installation and subsequent to drilling base plate drain holes. These racks were rated for loads of up to six hundred pounds. I used the racks to carry Kayaks each winter on trips of about 1200 miles each way. They are excellent for carrying Kayaks, though loading Kayaks is difficult for one average person. I have carried 12 foot dimension lumber on the racks and pushed the 600 pound weight rating on several occasions with no problem.I believe that these racks are one of the better choices in pickup racks because they are well made and will enable you to carry Kayaks or other long items with your truck, even if the bed on your truck is short. The price is reasonable and the seller promptly shipped my order. The only issues I have found with the racks is the poor grade of paint that they are coated with from the manufacturer and the lack of drain holes in the base plates. However, given the overall quality of the racks and the reasonable price, I would still rate the bars 5 stars because to get a better set of racks, a person would have to spend substantially more money.A word about installation: The base plates on the racks are heavy steel. I used 4 different 3/8 inch bits to drill a total of eight holes to mount the racks. I would suggest that you have several 1/8 inch bits available when you drill the drain holes in the base plates. On my vehicles, I had to carefully locate the base plates on the bed rails to insure that I had adequate room for base plate fasteners on the underside of the bed rails.
