Roof splitter...better front end aerodynamics
Big beliver here of DIY aerodynamics. The "pocket" in-between your TRUCK cab and camper cab-over is a huge source of drag and wind noise. Its like towing a parachute. A roof "splitter" will low...
Forum Discussion
Wayn's right. This precise roof-to-cabover inflatable boot topic discussion goes waaaaaaaaaaaaaaaaay back, and was prolific. Eg. in 2003 (10 years ago) in this very Forum, the following was discussed:
"I used a blow up boot on my last camper between the truck and camper. It worked great, but it rubbed the paint off of both my camper and the truck."
and,
"I have seen the boots used and the principal was great, but unfortunately they did not work as stated. Most I saw used had problems rubbing the paint off the truck and camper and another problem with staying in place"
and,
"I tried air up boots many years ago and they all ended up in the trash can. They rub off the paint and when going to and from the mountains the pressure in them keeps changing because of the altitude changes. A real pain!!"
....just a small sampling of the very negative issues with this route.
Go the tried and true route, with Sleepy's air foil system, here--> And here is Sleepy's post on how shapes affect drag, NASA--> . Those with square jack legs will experience appx 4.56 x the drag when compared with round jack legs (quite significant). Sleepy and I discussed the relevance of jack leg drag n relation to "the big picture", in our driveway, using our camper as an example, when he last visited us.
Sleepy is an alumnus of Oak Ridge National Lab (ORNL), and a World-renown inverter. Have a look... think you'll like it and his build/test methodology.
