Video Transcript for Stromberg Carlson RV Manual Pull-Out Step Measuring

Today we're going to show you how to measure for the RV manual pull out steps and attachment inaudible. Now the biggest difference between these steps is the depth of the bottom stair from the center of the attachment point at the top of the mounting plate. First, we need to measure the width of the stair assembly. In this case, it's 27 1/2 inches. We'll also measure the stair height which is 9 inches. The third measurement that we need to take is from the center of the step assembly here at the top at the cross bar and make a diagonal line straight down to the edge of the bottom stair.

This will give you the measurement that you need in order to correct stair. If your stairs aren't there, you'll measure approximately between the two mounting bolt holes for the stairs at approximately a 30 degree angle to obtain a measurement that will suffice the stairs that you need. Once you've determined the correct dimensions, you can go to our website and select the appropriate stairs for your trailer. And that will do it for how to measure for the correct stairs for your RV trailer.

I looked everywhere at these and this is the best price anywhere. Etrailer has all the instructions and videos to make it simple to install. I am upgrading from a 2 step to this 3 step to make it easier to get in and out. This is going to take just a little modification but still is easy. 76016


I am wanting to buySN-24-30 RV manual triple steps they would be 1312 inches from trailer . I have 201/2 inches from trailer to ground that would give me 7 inches from highway to bottom of steps when traveling would that be OK? Thanks,Tom Charlton

comment by: Tom C - 07/28/2013


That should be enough clearance, depending on how much your trailer moves on the suspension. If there is a of travel to the suspension or the springs are older and not as stiff, it might be a problem. But as long as the suspension is in order, you should be fine.

I assumed the process of replacing my rv steps was going to be a guessing game. Etrailer's videos made everything so simple. After measuring my steps according to the video, i knew what steps to order. I got the exact steps i need and they arrived in only three days. I watched the installation video and within 30 minutes, i removed the old and replaced my new steps. Price was great and the free shipping made the process even better. Steps are very sturdy and look great. Highly reccomend Stromberg Carlson RV steps.Thanks Etrailer. Just a reminder to all RV owners. FOLD UP YOUR STEPS BEFORE YOU GET ON THE ROAD. 88950

Arrived via FedEx in just three business days from ordering it. Exellent quality and perfect fit for my Keystone Laredo camper. Folds in and out better that the original equipment stairs.

Very high quality steps. Possibly better than I needed because of the weight. Outriggers ordered to enable installation not really heavy duty enough to support steps properly. Overall, I am very pleased with my purchase, especially the service and promptness of delivery. Etrailer staff very helpful. 23612

Good solid product....easy to install. Even though my old steps were bent up pretty bad, these still installed nicely. Save the nuts and bolts from the old steps. Use a jack and board to steady the new steps while you install; and a deep socket wrench should do the trick. 62502

Expert Answers about RV Manual Pull-Out Step - Triple - 7" Drop/Rise - SM-24-30Do you have a question about this Enclosed Trailer Parts?

  • Installation Dimensions for the RV Manual Pull Out Steps and the Attachment Outriggers
  • We have 3 sets of Manual Pull-Out Steps with three steps, see links. The difference between the 3 sets of steps is the depth of the bottom stair from the center of the attachment point at the top of the mounting plate, see photo. You would need to measure your steps and compare mounting locations to see if the steps can be bolted on as a direct replacement or if you would need to move the mounting locations on your RV. All of these steps are 27-1/2 inches wide overall and the mounting...

  • Dimensions of Stromberg Carlson RV Steps # SM-24-30
  • The Stromberg Carlson RV steps really are not designed for the purpose you describe. This does not mean that they will not work, but there might be some fabrication work involved in attaching them to the bottom of your van. As you can see in the diagram in the instructions I have linked to, the # SM-34-30 step unit is about 13-1/2 inches tall when closed. When fully folded out, the steps will be about 16-1/2 inches tall, measured from the top of the assembly to the top of the bottom...

  • Need Replacement Light Lenses and Steps For 2000 Jayco Quest Travel Trailer
  • For replacement lights for your 2000 Jayco Quest travel trailer you will want to order by part number on your lights or by the size of the light. The SAE number on the lens stands for the Society of Automotive Engineers. The SAE part number is not the part number of the light, it is just a number on the lens that means that lens has passed SAE guidelines. These part numbers are usually on the lenses of most all trailer lights. If you can send me the brand name (Bargman, Peterson,...

  • Measurements and Installation of Manual RV Pull-Out Steps
  • I have included a picture that shows the measurements of the manual folding step, # SM-24-30. Because of the way the steps are designed, you would not be able to pull out just 2 steps. You would have to pull out all 3. I have also included some video links that will help explain installation and measurements. On the top the center to center distance between the mounting holes is 26 inches. For a 2-step version use # SM-24-20.

  • We do have a manually operated pull-out step, part # SM-24-20, a 2-step unit that features a 7-inch rise between steps. This might be a better choice and hopefully the 1 inch difference will make a difference for your wife. There is also a 3-step unit, part # SM-24-30 that also has a 7-inch rise between steps. To determine which unit you need, measure from the mounting surface where the steps would attach down to the ground, and compare that distance with the total height of each...

  • How Wide is the RV Manual Pull-Out Step # SM-24-30 and what is the Diagonal Measurement
  • The width of the step is 24 inches. The only time the number 30 is mentioned is in the part number and it does not reflect any of the dimensions of the steps. The # SM-24-30 has a diagonal measurement of 41 inches from the top corner to the bottom of the bottom step surface. Check out the picture I attached to see the dimension I am referencing.

  • Availability of a 3-Step Electric Step for Travel Trailers
  • You have a valid concern about operation of this product with a partially depleted trailer battery. I researched similar products and I did not find any specifically intended for travel trailer use. One solution is to procure a separate 12V automotive battery for operating the steps, provided that your trailer has a suitable place to locate one without requiring excessively long wire runs or the risk of causing pinched or shorted wiring. In this scenario a battery charger might also...

  • Replacing 2 Stair Steps with 3 Stair Steps on a RV or Trailer
  • The overall width of the 3-step stairs # SM-24-30 is 27-1/2 inches but the mounting holes are spaces 26 inches apart on center. It sounds like you would have to do some minor adjustments on the RV to get these steps to fit. I have linked a couple of videos to the right on measuring and installation of the steps for you.

  • Would the Stromberg Carlson RV Steps # SM-2410-39 fit a 2002 Holiday Rambler
  • In order to determine what would be the correct replacement steps for your 2002 Holiday Rambler you will need to get the dimensions of the steps that are currently on your trailer and compare them to the picture I attached that shows the dimension of the RV Steps part # SM-24-30. If the dimensions match what is in the picture the # SM-24-30. I attached a measuring video for you to check out as well as an install video for the steps that should be very helpful.
