I will get out and give you exact measurements when I get a chance. Definitely not as much as the F150 now that the RamBox is there, but when I saw that feature at the dealership- I knew that was a must have for all my tools and carry-on items that normally bounce around in the backseat- plus there is add ins for my rifles and fishing rods to ride in there secured. I don't have the wheel well humps to get around either- so that helps. I have a utility trailer for hauling lumber and supplies that I was already using, so it was an easy trade off for me.
I'll get back to you on that!
I have an ATV that I haul from time to time. With the bigger tires, I believe it's 49" wide. It fits fine in my F150 with the tailgate almost completely closed with a 6 1/2' bed.
I've been on the Ram side for several years now. They truly have been the best Trucks I've ever owned. Originally my entire family bleed Ford blue, but we began having problems after problems with them and the 1-800# really didn't give a *****. So our problem was solved. We became Ram owners. It wasn't until 2 yrs ago when my brother bought a new problem free F250 and F150 that I considered coming back to Ford. It did take quite a bit of convincing for my wife to agree. There's a lot riding on our new F150 to keep her convinced.
I was very close to getting a Ram Limited. At the end of the day competition is what keeps trucks so close to one another. For me the deal breaker was really just price. At the time the Ford was a better deal and the dealer was super nice. Having never owned a Ford, I decided to pull the trigger and see what happens! I can totally see getting a Ram though. That 2013 interior is so nice! Best of luck!
