Demountable camper group

Hi just bought the x large version of this for my
camper and arrived in 4 working days,

its self assembly decent quality, and can be modified to the size you need and at a good price too https://m.ebay.ie/itm/Camper-Motorhome- ... %7Ciid%3A1]

Interesting, like to see that installed afterwards

Ha! is that "interesting" wtf that'll never work ! or ??
I plan to mount it flat to the roof, I'm dis-inclined to drill through the roof of my *Ranger Demountable* so thinking of attaching broad surface aluminum plates and using Tec7 or some such, I have excess aluminum sheeting I might fashion up a wind deflector from and add to the front of the rack .

Can see from the picture properly but any way of avoiding a main dealer and his 'specific' aftermarket prices can only be good news
