I just installed Stromberg Carlson Manual Pull-Out Steps for RVs - Quad - 7-1/2" Drop/Rise - 750 lbs that I purchased from etrailer.com and I could not be happier. I replaced the standard 3 Steps on our new 2014 Forest River Cardinal, model 3850RL and it could not have been easier. I removed four carriage bolts and two self tapping bolts and lowered the unit with a jack. I raised the new steps using the same process and the bolts aligned perfectly. The carriage bolt holes were exactly the same and the same bolts went in with no problem. The only tools I used were a ratchet set, the jack with a board to hold the steps, and an electric drill to reinstall the self tapping bolts. The only challenge was breaking the carriage bolt nuts loose, needed a short cheater bar. Start to finish was less than 45 minutes. By the way, my wife is very happy with the new steps.
