Currently I have a 16 foot bumper pull trailer, but I am curious if anyone has any experience with a 20 foot or more gooseneck? My main concern is getting into parking garages.
What kind of experience are you looking for?
I regularly drag around a 40+’ gooseneck. The best thing about a gooseneck trailer is that you can get it to almost 90°to the tow vehicle while backing up, or turning around. If you’re going to move up to a 20’ gooseneck from your 16’ bumper pull, you should be fine taking it anywhere you have taken your current trailer.
The only issues you might encounter is maybe having to swing a little wider initially.
Just remember that the goose neck will not start turning as quickly as a bumper pull will while backing up, you can just turn tighter.
