Using a 48" Extension on hitch

Ok folks I did not want to start a SAFETY discussion. I've had this Reese Tow Beast Class V hitch for many years (since 2005), used hitch extensions on it, that's part of the design of the thing, and am aware of the drawbacks and the advantages.

My question is: has anybody used an extension a few inches longer than necessary to provide clearance for the TC door?

Thanks again.
