Pillar-less curtainsider specialist Lawrence David has a number of off-the-peg options for either new trailers or retrofitting to existing LD trailers, including: ● an aerodynamic front bulkhead moulding: cost around £450, with a fuel saving of 1.6% and a payback in about nine months; ● rear roof diffuser: cost around £350, with a fuel saving of 1.2% and a payback in about 11-12 months; ● full contour side guards: cost around £1,850, fuel saving of 1.7% with a payback of around 2.5 years; ● side guard in-fills: cost about £1,000; fuel saving of 1.3% with a payback in approximately 2.2 years; ● flush rear doors: cost around £380, minimal fuel saving but can help improve mpg; ● a rounded rear under-run, which costs about £120, with “a minimal fuel saving but again it can help improve overall mpg”.
LD says: “[The above] are all based on add-on costs to a new build standard trailer. Retrofitting to existing trailers may increase the cost slightly due to additional labour time to modify certain existing areas.”
