Hi m8,
Not an O/O myself but have been around trucks for a while & know the hassles 
I use a one man band to maintain & repair my âtoysâ & he has always been good to me. i do get put to the back of the queue a bit but then mine isnât a working vehicle so doesnât matter & I KNOW he would come out if i got in trouble. APS March, not got his number handy but if yo want it, email me & I will send it off to you (my email info@signworkshops.co.uk). APS is based in Doddington but works mobile. The other one that comes to mind out your way is Charlie Welbourn, I know he used to do all Rocma work & Mr. Griggs can be very particular & doesnât throw money away, so I assume Charlie is reasonably priced & good (certainly a happy sorta bloke if you want winding up 
)
Dunno if itâs any help, but best i can do 
John
