This review is for our purchase and installation of the Doggo ramp rail kit for an earlier production ramp. The ramp was the second one we bought, after first buying a cheapo clone of this one. Let me start by saying, don’t do it. Save your money on the cheaper stuff, and just go ahead and get yourself a quality Doggo ramp. It costs a little more, but you’ll be glad you did it. My wife felt like we needed to add the side rails to this ramp, after our little Hanna began to wobble a little bit going up and down the ramp. We ordered the kit, and were a little bit bummed out when it arrived, because we didn’t initially know that the kit is made for 2nd generation ramps, which means that it wouldn’t just bolt on. I realized that I was going to have to do some measuring & drilling to make this thing work. Not thrilled, but I told myself that “I can do this”. The kit comes with three rails, so you can install all three but you won’t want to, because your buddy will be at a dead end if you do. We looked at our particular application and needs, and decided that we needed both side rails, but no end rail, so they could exit the ramp at the top and walk out on to the sofa. I made my measurements, drilled my holes, and installed the first side rail. After installing the first rail, I first thought that I had been sent two left side rails, and no right side rail. After very carefully studying the diagrams, I realized that there are no left and right side rails. They’re both the same. Well, I’m just not digging that, so I took the second side rail apart, and reassembled it so that the rail looked like it was made to be installed on the other side. This really isn’t a structural problem but it makes it look weird, and I just didn’t like that, so I fixed it. We slid it into place, and used it for a day or so, but due to our particular application, we (I) didn’t like how the one side rail was just a bit too far up toward the top of the ramp, so our Dewey couldn’t just make the turn and exit the ramp on to an ottoman where I sit. He likes to step off the ramp on to my extended legs on the ottoman (we refer to this as “riding the leg hammock”), but with this side rail in position, he was unable to do so. After thinking about this for a while, I decided that I would remove the previously installed side rail, and install the shorter rail that was intended to be used for the end of the ramp in its place. This would give maximum protection from the middle of the ramp down to the bottom, and would allow our Dewey to climb the ramp to the top and exit on to the ottoman, if he chose to do so. This may not make a lot of sense to those who can’t actually see it, so I am going to try and include several pics of our particular application, and the various ways I modified the ramp. The end result is a ramp that is fully functional for our babies. The quality is exceptional, and it looks great! We really love it! I apologize for this review being so long. It may be boring and useless to some, but I try to be thorough and concise with exactly what we experienced, and the steps I took to overcome our challenges. I suppose the ultimate take away is, if I can do it so can you! Thanks, Ryan for loving Crusoe & Daphne enough to create this marvelous ramp and rails. We love ours to the moon and back too, and just want to offer them the best products available.
