They're definitely ally but I've polished them up a bit.
Originally they were painted a horrible dull brown like the panel between the side windows. I stripped the paint with nitromors intending to paint it white but then thought it looked pretty neat so decided to polish it up and leave it like that. I wondered whether it was legal (reflection of headlights behind) but there are loads of american style trailers that are polished aluminium finish so i guess it's OK.
Heres wot I did 2 my camper.. A few rattle tins of spray paint an an graffiti artist... Had her for about a year now,, she's been the length and breadth of the country.. Brilliant festival bus.............
