But how much should these things cost, you haven’t mentioned a price what would be a fairer price?
Difficult to define fairer?
Two well known proffesional suppliers prices for a 'standard' single 40' RO 650 ltr van mount fitted....
Supplier (a) £3995
Supplier (b) £2100
Supplier (a) also sells a fitted single 40' RO van mount that is heated for 7k.
Supplier (b) doesn't do one.
My guess, based on no more than plucking a figure out the air is that it should easily be possible to have a fitted heated system similar to above for 3.5K.
