@el Rojo - It took me a minute to figure out what you meant by "S&B home." ;D
@titrtyca - if the exterior entry door holder is missing on your RV, we will cover the installation under warranty as we intended for it to be installed; however, your unit was not designed to be used with a gas strut at the entry door. A gas strut at the entry door would be considered an aftermarket part and if installed, a unit modification (which is not covered by warranty). As a representative of Grand Design, I'm respectfully declining to discuss modifications to our units (as my participation could be wrongly perceived as tacit approval). Thanks for your understanding. ~ Janice
