Recommendation For a Solid Step for 2010 Keystone Cougar 5th Wheel

How well RV steps like the Lippert SolidStep Item # LC791572 fits your RV depends on the size of your trailer door opening. This SolidStep 3-step model fits doorways that are 26 inches wide to 29-7/8 inches wide where there is a threshold height of 27 inches to 36 inches from the ground.

A similar 4-step model, Item # LC791574, fits a doorway width of 26 inches wide to 29-7/8 inches wide with a ground to threshold height ranging from 35 inches to 44 inches.

I looked several places for information on travel trailer door sizes and heights and did not find a specific match for your 2010 Keystone. Generally RV manufacturers use standard sizes for things like doors. Based on the photos I found, I think one of these steps will work for you. You will just need to do some measuring to figure out which one is best for you and your situation. When doing your measuring, be sure to include the mounting hole so that you can get steps with matching holes. Since Lippert manufactures most of the trailer frames and aftermarket products, one of these should be a good fit.

If you send me your current mounting hole dimensions, I can make a specific recommendation.

The # MR88RR will work perfectly on your Keystone Cougar. This assembly is made for 23-3/4" to 26-1/4" wide doors.

So I ordered a 24 inch solid step dare watching videos to install it looks like I should have measured the length of the entire door and not inside flange to inside flange will this mean the stairs wont work cuz I went from inside to inside to get my 24 in measurement I was given bad information from a camping supply store outside of etrailer on how to take measurements for the stairs will the 24 in stair work or does it have to be the width from the widest point of the door to the widest point of the door

You would want to measure the inside width of the doorway (the opening where you actually walk through - not any part of the frame itself). It sounds like this is how you got your 24" width so you should be good to go. If not, please just let me know and we can go from there!
