Just a quick add to my post #14 above, regarding hitch weight as a percentage of total trailer weight. In that post, I said
"
... the widely agreed number for tongue weight is 10%-15% of the loaded trailer weight.".
That is the number on every trailer web page I've ever seen.
Today I noticed that the Tesla web site
https://www.tesla.com/ownersmanual/m...E27E3B4D8.html
says
"The tongue weight is the downward force that the weight of the trailer exerts on the hitch. It must be at least 4% of the total trailer load."
Four per cent! I've never heard a number anywhere near that low. But it would explain why the Tesla-and-Airstream videos seem to say it is OK to run with such a low hitch weight. Is it really OK?
Even the Airstream web site, at
https://support.airstream.com/hc/en-...on-hitches-101 says
"...the proper tongue weight of the loaded trailer should be ... 10-15 percent of the loaded total".
So I am not sure why Tesla thinks that 4% is OK. Maybe there is something different about Teslas. Or maybe it is just hype. I personally wouldn't come anywhere near doing it - but that's just me.
