Hi,
short term lurker. Owner of a 33' long 11' high 7.5 ton (16,500lb) motorhome / RV thing.
Aerodynamics of a brick, slushbox auto, 6 litre straight six turbodiesel, 175bhp, old skool bosch diesel pump (so can run on veg oil) 1996 build - costing the original owner £150,000.....

Already done a rear diff swap for the highest possible ratio available - now tops out at 80mph (yes).
Plans include:-
front air dam - any ideas as to what front approach angle I should go for?
Cover rear wheels
Belly pan?s
Boat tail, with foldable sides on pneumatics for tight spaces.
cameras instead of mirrors - this has just been made legal in the UK this year or possibly the 'hang out the front' type you see on inter city coaches
currently getting 11.5 UK mpg (our gallons are slightly bigger 1 ukg = 1.2usg) and our fuel is £1.45 per litre = 2.36 dollars /litre = $8.94 a us gallon...
