Stromberg Carlson Ladder Extension

SAVES YOUR KNEES - When you need to access your RV's solar panels or AC, that first step up onto your existing rear ladder can be a doozy. To help make that bottom rung more accessible, attach this extension onto the end of your ladder to help close that distance to the ground. This makes it easier and safer for you to climb up to your RV roof, preventing you from putting too much strain on your knees, hips, and ankles.


Stromberg Carlson Ladder Extension

SUPER LIGHTWEIGHT When you're done working on your RV roof, the aluminum ladder is lightweight enough for you to carry by yourself and tuck away into a smaller closet, cargo compartment, or wherever else you can fit it.

i use this in conjunction with the Stromberg ladder that I installed on my Thor Compass which obviously didn't come with one. The step up to the fixed-in-place ladder is too high for safe access so this extension is the perfect match. Easy to use, easy to store in place with the ladder using the support brackets on the top of the extension and then holding in place with bungee cords.

I use the ladder frequently because I have solar panels on the roof to be cleaned and inspected after many miles on the road. The ladder mounted on the rear wall is sturdy, the adjustable feature allowed a perfect fit. The extension piece works well. I would buy both again. I wish I’d had the extension for motorhomes I’d had before.

Extremely fast service.
I have a Dutchman Voltage V-3905 Toy Hauler. etrailer recommended that I get the LA-401 ladder and the LA-148 extension, as the original 110" ladder is not available through etrailer, and cost over $300 from Dutchman through Camping store. The two items came to just over $100 so I got the free shipping. I placed my order yesterday at about 2pm. They were delivered to my house by UPS at 10:14 this morning, wow!
They look very good, I don't plan to install them until this spring when it warms up a little (presently we have 15" of snow on the ground). I will add an update and a photo afterwards.
by:
Just what we needed. We are very happy with the quality. Arrived in the time frame expected. We will be ordering from etrailer in the future.
HAPPY CAMPER

We Love it. No need to lug around an additional ladder just to get to the RV ladder

We bought this ladder thinking we could replace our broken RV ladder. My husband had to improvise the connections. The durability should be fine.
by:
Shipping was fast & no damage. Ext. Ladder (LA 148) will work fine. The LA 401 Ladder is okay except the attachment arms are too short for the odd shape of my RV.

  • Rear Ladder Replacement for Tiffin Allegro Red Motorhome
    The Stromberg Carlson RV Exterior Ladder part # LA-401BA is our best replacement exterior ladder option for a Tiffin Allegro Red Motorhome. It measures 99-1/2" tall and can be trimmed shorter if needed. That said, there is also an extension for taller applications, the Stromberg Carlson RV Ladder Extension part # LA-148. The standoff locations can be customized so you may be able to utilize the pre-drill holes from your old ladder as well.

  • Recommended Ladder Extension for a Motorhome
    Hey Patrick, congrats on your new motorhome! We don't have an extension ladder made specifically for your 2004 HR Scepter but so long as the vertical supports of the current ladder are 1" diameter you can use the Stromberg Carlson RV Ladder Extension item # LA-148. This extension is 48" long and has 3 non-slip rungs which will allow you to easily reach the ladder on the back of your coach. It uses rubber straps that wrap around your ladder's uprights to secure it. One of the best perks...

  • Solution for 2-Piece Exterior Ladder for 2017 Winnebago Forza Motorhome
    I do have a solution, but the ladder you're describing appears to be unique to Winnebago with no direct replacement options. The closest possible thing would be to use the Stromberg Carlson Exterior RV Ladder # LA-401 along with the Stromberg Carlson RV Ladder Extension # LA-148. You could cut down the regular ladder so that it sits as high as possible for the 48" extension to still attach. Then, you can remove the extension when not in use. Keep in mind, the extension is designed to...

  • Replacement Ladder Needed for 115
    I do have a solution for you, but unfortunately we do not have any ladders that measure 115" by themselves. Instead what you can do is install the Stromberg Carlson RV Exterior Ladder # LA-401 which is 99-1/2" tall and then use the Stromberg Carlson RV Ladder Extension # LA-148 which is 48" tall. You can cut the ladder to fit your needs, but I recommend just using the full 99-1/2" and then connecting the ladder extension to the part of the ladder that best suits your needs. As you can...

    If the 30-1/2" of the Surco RV Ladder Extension # SP504L is not long enough we do have another option available, the 48" Stromberg Carlson RV Ladder Extension # LA-148. This extension will mean the last step will be about 10 inches from the ground, which is going to be a much more manageable last step and hopefully help prevent you or your husband from slipping.

  • Replacement Ladder Support Peg or Stand-Off for Stromberg Carlson RV Ladders
    I am not sure which piece constitutes as a spacer in the Stromberg Carlson ladder # LA-401. It could be the stand-offs, the horizontal part that goes between the back outside wall of the RV and the ladder. If that is the part you are looking for it is # 8535. Or do you mean an extension like # LA-148?
