Previous owner must have considered himself Mr. Fix it ( he wasnít!) Back kitchen (heavy ) hatch has NO gas powered shocks to hold hatch open . Owner said huge wind tore hatch open and he removed shocks. I cannot find size( length) or strength ( in lbs) size to replace. No brackets or anything . Tried 27 lb shocks last night but too short and small RV place next to me canít help without knowing length and strength . Can anyone assist me ??? Please??? Searched numerous sites and googled shock videos to try to determine weight/ length to no avail.
I think you are looking for a "strut".
It sounds like you've already established a length that is not long enough.
Try measuring the distance between the two sets of bracket mounting holes with the hatch open. This might require a helper and/or a board to hold the hatch completely open while you measure.
Similarly, try and measure the distance with the hatch (nearly) closed.
That will be a good start. After that, you'll need to find a sympathetic dealer who will help estimate the lift strength required; you already have an idea of what is too little strength, so that's a start.
Another option is to try some different RV forums. Your trailer is unlike the ones that we focus on here, so there's probably no one here who has one like yours.
If you try TNTT.com and RV.net or other RV forums, you might find someone who owns a similar trailer that will look at their struts and post a picture or copy the text from the strut for you.
