Jaycocreek - the issue with your original post supporting the use of supports is the bit where you insinuated that other POVs were nonsense. That is argumentative as are many of your follow on posts. And that is why you might be catching flak for this.
We get it. You like your supports and that is good for you. Many of us who are advocating against their use have no direct experience exactly for the reasons stated. That is reasonable and is not nonsensical. Maybe instead of posting an argumentative post you can consider the reasons posted then show, through your actual experience, where these fears might be unfounded. That would be positive.
As for the original question by the OP - I think that it has been answered among the 3 pages of responses, i.e. read the manual for the RV. If no manual is available call the manufacturer.
