You don't need to ,once you tax disc indicates you are classified as a camper/motorhomes you pass trough as a car . your best go trough a lane with an attendant .if any doubt tell them you will put the kettle on and offer them a cup of coffee while the sort it out
No tax disks in U.K./N.Irl any longer....... but as you say, go to an attended lane and they will sort any issues.
They are actually very efficient and courteous any time I deal with them.
For what it's worth, my motorhome is UK registered, I have a video account with eflow for M50 journeys and I pay the car rate always plus a discount of 50c per journey for having a video account.
Also, I have never paid anymore than the car rate at an automated or attended barrier.
My motorhome is 7.5m x 3.2m x 2.3m and <3500kgs.
