Recommendation For 4-Step Replacement For 2009 Bighorn 3400RL 5th Wheel Trailer
Question:
I need a replacement step for my 2009 Bighorn 3400RL Heartland 5th wheel trailer. Vertical pitch is very important, the closer to 6 inch is better for our bad knees, step stability is also a factor. Aluminum? Steel?

Because you want stability and have some knee issues, I recommend something like the Torklift GlowStep Revolution Scissor Steps w/Landing Gear-4 Steps, Item # TLA78004.
The Torklift, Item # TLA78004, has aluminum steps that are lightweight, fold up for storage, and are 8 inches deep x 22 inches wide. You can fine tune the height and level of stairs with the built-in landing gear legs which also make these steps more stable. The mounting base dimensions are 27-7/16 inches x 12 inches deep. They have a 7-1/2 inch drop/rise and the height from top of step opening to ground is 32-1/2 inches - 40 inches. Glow tape lights each step at night which is much safer. Aircraft-grade aluminum and stainless steel construction. Made in the USA.
For even greater stability, I recommend adding a Torklift GlowGuide handrail, Item # TLA7621.
In order to find the correct fit and get the right steps, you are going to have to do a little measuring. You want to start by measuring the width of your stair assembly, followed by the height from stair to stair. After that, you want to measure from the center of the step assembly at the crossbar to the diagonal line at edge of the bottom stair. I have attached a video to help with your measurements.
Send me your measurements and I will make a correct recommendation that best meets your needs.
