5th wheel dollly

Been a member for a while but never posted (shame on me)…anyway here’s what I want to do I have a 8 wheeler hook loader and want to pull a trailer, But want to use my 26’ artic trailer so was thinking about a dolly that I could slip under the semi trailer and tow as a drag…now here is the question does the dolly need an MOT and plate as in my mind it’s an appliance not a trailer as it can’t carry any load until the semi is attached which has a plate and MOT

Which brings me to my next question has anybody got a dolly for sale or could I make my own (have a well kitted out work shop) using a tandem axle from a tanker trailer complete with its plate and convert it from a trailer to a dolly by taking the bogie from under the barrel replacing with a 5th wheel coupling and fitting a draw bar to it

Cheers in anticipation Mogman

You sound like Joey Barnes/King of Obsolete from Ice Road Truckers.

Can’t answer your question, but it sounds cool what ever your trying to do. [emoji41]
