I needed an extenton for our RV ladder and could not find one that was the right lenght. However this extention is stong and will work with a little adjustment.I love the hooks on the top you can put them to the inside or out side of the ladder. This ladder was a foot short of reaching the ground, our trailer was 58" from the last step to the ground and the ladder was 48". I also bought the replacement pegs for the short ladder (30 1/2") and plan on drilling a hole to mount to this ladder to line up with the bumper for more support. When it is finsihed I will share a picture.

It is working great with the little adjustment the I made.

by: Jeffrey J. 10/13/2016

Works nicely as the ladder closely resembles the steps on my coach ladder. But I was surprised the extension is so flimsy. I was expecting something much more sturdy feeling. Will do the job.

Still a nice addition to my RV ladder. No further complaints or issues one year in.

by: Mark 05/20/2022

Works well. Well made. Long-term -- we'll see -- but I'm hopeful.

Very helpful to access the roof of our RV. The ladder that is part of the unit is not long enough.

The ladder extension works exactly as pictured. It extends the usual ladder down to the bumper, where it is much easier to mount than that high step on the back end of the RV.

The structure seems sturdy (I weigh 225 lbs.). The picture shows some black caps over the horizontal pieces that brace off the bumper. Mine had a cap that inserted inside the aluminum tube and would be barely visible in the picture. I improved the design by putting two heavy rubber furniture feet (like on the bottom of a crutch) over the two black caps to make it much more robust.

Also, the lock for the hooks are 1/4-20 screws with phillips screwdriver slots. I went to Ace hardware and purchased knobs to mount on the screws so I wouldn't have to hunt a screwdriver every time I stop at a campsite (or leave one).

I am pleased with the product. While traveling, I will lock the ladder extension on a higher rung of the fixed ladder and hold it tight with a bungie cord. That way, I can leave the 4 foot step ladder I usually carry in the cargo compartment at home.

I don't really know how the extension will work until I install the ladder I bought. I believe it will work fine but just don't know yet.

The extension ladder did not work well for me. I believe it would work for other folks just fine. Our camper was to high from ground to work. I used part of my older ladder to make my own extension.

by: Don L 04/10/2022

Ladder received as advertised: very good quality product, all parts as required, and adequate instructions. Installation without major problems by one not particularly mechanically inclined. I have not put it to the climb test yet; however it has a "rock solid" feel and looks really nice on our RV.

by: Lee M 11/09/2019

Got package ok, problem was two small set screws that hold legs out that rest on the bumper were loose and rolling around in the box they fell out when I opened box and at first could only find one, did find other other on floor but they should have been tapped in with the Allen wrench so they could not be lost. Other than that it fits and works great.

by: dan 08/07/2017

Ladder Extension works great and is very strong. I also like that it's adjustable the way it lies on the rear of the coach.

It was supposed to fit my RV but it didn’t. Cheaply made as well.

I wanted to ask how it did not work with your RV ladder? Was it too short?

by: Dave 05/21/2020

item arrived exactly as described, and on the exact date. It is sturdy and well built, attached easily. I look forward to using this for several years.
