I quote below from an email sent by Dixon Bate in response to my extensive telephone enquiry – they were initially reluctant to quote, thinking the Wayfarer was heavier than it really is!
Dear Dr Maynard
I have checked on the unlaiden weight of the road trailer with rollers and it comes out at 70kg.
I have attached a photo of the said trailer for you to mull over.
The road trailer with rollers costs £457.89 inc vat
