they have been around for quite a few years now, one issue i would have thought was, if you change trailers regularly, you are bound to pick up a trailer that has been coupled to a conventional fifth wheel and the underside is covered in grease, surely, this would make the teflon fifth wheel a waste of money
I had one on a race transporter for years, great for that job where you always use the same trailer and rarely uncouple and didn’t want grease getting all over the place.
I can’t really help you how they’d work in general haulage work, although I don’t they’d be worth it if you are pulling different trailers unless they are all grease free.
well the second trailor on my b-train uses a teflon liner…and i notice no difference in handling,cleaner as no grease to worry about…as the trailor is very rarely uncoupled it looks as good as new(3yr old)
only thing if uncoupling/coupling up you have to be a bit careful as not to damage.
Salserve (division of Christian Salvesen) had teflon sheets
they never swapped trailers all done to provide M&S with
a clean image
the fridges ran on gas
Our two volvos have had these on since they were new (57&58 plates) and have been no bother at all, at bit of grease on them does not make a difference theres always a bit of grease in the middle, as the jaws still have to be greased,also care has to be taken when connecting up as i have heard they can be knocked off,a bit of education on how to pick up a trailer with an air suspension unit helps.
Our are bolted on with 10 8mm flat top special bolts.
