Advice needed to mount and transport a 30 foot A class carbon mast on a 27 foot long motorhome. I could raise the trailer front mast support to clear the RV roof but that will put the mast tip pretty close to the 4 metre local bridge heights and still mean plenty of rear overhang off the trailer which can attract unwanted police attention. Can anyone offer ideas on off the shelf racks or secure clamps I can purchase or fabricate?
