Why you don’t double tow with travel trailer

If set up right it can be safe to double tow ball to ball. This was not set up correctly.

Yeah a better lead in would have been "this is what happens when towing two ball/bumper trailers and their not properly set up".

I see lots of summer time double towed TTs/some type of water craft on trailers around here track straight down the road.
The tow vehicle or the TT was in no danger of going over....just the improperly balanced single axle trailer.
