Here’s one for you.
Would a cab air kit (side deflectors & roof job) be any benefit on a Scanny Series 4 R Sleeper unit if pulling a step frame lowloader trailer with stand up ramps.
I’m guessing that the cost of adding a set would not be recouped by any fuel saving but I was reading some of DonBurs claims about the teardrop trailers. It’s surprising how altering that airflow can change things so much.
