I responded in another recent thread where somebody was asking about a lift for a bed. I told the story of talking with a couple that pulled in next to us in a RV park. I started a conversation with the couple as I noticed the lift they had on the door of their motorhome. Since I once drove transit buses, I was interested to see the lift work.
They had one where you sit down. There are ones that have platforms on which you can stand but from what what they told me, I think he said they are more expensive (because of the need for handrails?? I don't know).
One thing that I found disappointing, however, is that the one they had was excruciatingly slow. They told me that all the lifts from various companies that they looked at were equally slow (videos below will demonstrate how slow they are). Again, I was used to operating ones on transit buses that by the nature of what they're used for are required to be sufficiently fast in their operation.
My notes say that the one they had was made by Coach Lift in Tempe Arizona. I remember that they told me Coach Lift was great to work with as they would customize the lift in any fashion you would like.
The other reason they preferred Coach Lift as that they were from the Las Vegas area and it was a relatively easy trip to Tempe so was more convenient than going to the Midwest where the others they looked at were made. I think they told me that they also preferred to have the manufacturer install and customize it for their needs so didn't want a manufacturer's dealer somewhere to install it.

Here's one from another manufacturer that has a platform to stand on and grabrails to hold that I just noticed as I was looking up the website for Coach Lift ...I'm going to assume that the Burr will be more expensive than the Coach Lift:

They can ship you the lift so you can install it yourself but they urge you to have it professionally installed for safety reasons and they can recommend an installer in your area.
