I've used the Twistep on a number of vehicles. I have two of the new style and it's much improved over the older version. My rescued Golden Retriever is 10+ years old and the Twistep makes it much easier for him to get into my Jeep Wrangler or Chevy Tahoe. If you've got a hitch receiver on your vehicle installation takes a few minutes and the adjustable height means it will fit almost all vehicles. I had to drop down one increment to clear the Jeep gas tank. My dog learned to use this quickly, with a couple of treats to reward he mastered using it easily.
Install Time: Under 30 minutes
This product is absolutely perfect for getting our dog in and out of the SUV. It is large enough to really work for this purpose and the manufacturer sent us a free extension to allow it to rotate under the spare tire.
