chopping:
toy haulers/car trailers frequently doulbe as weekend homes featuring kitchens, showers, workbenches, portable machine shops and the like. afraid hunching over is usually not practical. besides collapsible campers already exist.
more skin friction:
absolutely negligible. riding a bicycle at 10 MPH and then 20 MPH will give the average person only a mild appreciation for the momentous effort required for a vehicle having to displace air for a large slab the size of a car trailer (even if fitted with nose and tail cone) at freeway speeds. air takes the path of least resitance. just imagine instead of being forced to flow around it to be able to go right through. i would go for that!
more exposure to x-winds vs. smaller envelope:
numerous ppl have made the 2 club (entrance into 200 mph club while setting a record at speeds exceeding 200) at bonneville using just this hack. sidewinds are a frequent occurence on the salt. buddy o mine lost one retina when he impacted, quite literally, head on a lead acid battery which was used to power one of the trip lights entering the shot course speed trap. during subsequent events batteries were submerged. if these ducts posed any danger the tech boys would not sign off.
Ducting = more weight:
the idea i have been musing will weigh less than a cooler full of ice n beer and 2 lawnchairs to boot.
by design it is very light yet rigid, features integrated turbulence control, folds and unfolds faster than a teenager can answer a text. now that is what i call slick. tell you what i will do, just for the for the timid among us i will throw in a valve that will allow airlow to be suspended - just in case it gets skeeeeery
so Rick lemme ask you... it appears that you have plenty of room in there to take on a
Troll, however it seems there is concern about weight and by the looks of it 'thisone will crack 300 lbs ez!
