I'm not sure what the dimension is from bed side to bed side, but i would think it is close to a regular full sized truck, and i know that we have like 8-12 inches between bars in my F-150 when we have both bikes loaded.Just measure the distance where you would be able to mount it to a somewhat flat surface and order the size that you need. No, i don't get paid to endorse this product, I am just a happy user. Here are some pics of it installed in my truck to give you a better idea of what you will get as some of the pics on their website don't show everything. Be sure to click on the pics to get larger and clearer images. Sorry i don't have any pics with the bikes loaded, never had the camera around when we had them loaded before. But the best advice i can offer is take your time the first time around tying down so that you get everything routed properly. Also if you do decide to buy the CCR Bed Buddy, when you tie down two bikes, i would recomment using the stock truck tie down points for the outside tie downs and just use the center tie down point on the Bed Buddy. The bar is a straight forward install with just 3 holes to drill and then large expansion nuts to hold it in place. Another thing to keep in mind if you are going to be hauling a bike in a full sized truck often is to get a get set of ramps. You can load with one ramp if you will always have a buddy around to help you unload and load. I just bought two ramps so i can load and unload by myself. I got the 110"ramps from this site
http://www.atvramps.com/folding_dual_ramps.htm . I have no complaints on them as of the last 2 years i have had them. Yes they are expensive, but they are some of the longest ramps out there that are made out of aluminum. The length is needed to make it easier to load and to guarantee that the lower fairing doesn't scrape. Plus if you ever decide to put a small lift in your truck, you will still be able to load up. Also, a good set of ramps should last nearly a lifetime if you don't abuse them or loose them. That is enough of my story and what i use. :bitchslap
