Gotta say from my expierience £2100 sounsd way too dear.
Had a new Camper Canvas AND Tonneau done by Flexicovers (ok a few years back) AND all stainless work for a 28ft Rinker for £1700.
Was an absolute cracker! - I know cos I saw the old girl on eBay a few months back and the canopy is still on there and still looks like new! (about 9 years later).
I'd shop around a bit.
