RE: Yet another Air Dam/Spoiler/Airfoil thingy

Took the camper off yesterday. NO BUGS first time ever.

RE: Yet another Air Dam/Spoiler/Airfoil thingy

This is always an interesting experiment and with the current price of fuel important. I added my deflector last November that was made from fiberglass panels around Sleepy's ideas. We did not notice a noise reduction, but then I have read that one has a very short memory span for noise, and our firsts trips were around Phoenix rather than on the highway. Last weekend I got in a fuel test going from home at 8300' over two low passes and down to about 5000' east of Denver and then back. A trip of about 160 miles each way. I had the cruise set at 60mph both ways and of course take it off climbing the passes. Result was 13.3mpg as compared to my long term typical 11.7 at an normal 62mph. I regard that as a great change. Rig ismy 2006 Duramax with monstrous Host Mammoth.

RE: Wind Deflector

Beagle- look at the 3M double sided tape used to hold solar panels on available at the hardware in several strengths. Have mine done, just need to get to warmer weather to put it on as camper has to come off. If it quiets down the buffeting I'll call it a great success.

RE: Wind Deflector

And the winner is HMS Beagle. When you have a fiberglass shell with a wood backing and you want to put a screw into the backing an oversize hole should be drilled thru the fiber glass only because the higher temperature expansion rate of the steel than the fiberglass will cause the fiberglass to split. So the question is wll the same thing occur with these composite skins? Many years ago we had a member named Sleepy who figured out how to do these wind deflectors out of plastic gutter covers. They worked quite well to prevent the air steam from hitting and flexing the front of the camper shell quieting down the ride in the cab and also deflecting the insects that get almost embedded to the camper wall. The holes in the gutter cover also prevent a low pressure area forming behind the wall which can be an issue. When driving a barn door down the road, the only thing that I know of that helps fuel mileage is keeping your foot out of the turbo. The closest "big" town is 12 miles away and with a road that appears almost flat is 1300 feet lower and when the road west of the driveway heads up 3000ft to Monarch Pass. Staying out of the turbo is impossible. On the other hand when I roll 4000 ft down hill toward Canon City my fuel range drops by about 6-8 miles in 60 miles. The design is really quite simple. Following Sleepy's concept my front panel will be 16" wide fastened in the center to the front bottom seam of the overhanging bed then taper back about 18-20 inches to the edge fastened up to the underside of the camper. The panels are pop riveted to some 1x1 LW aluminun angle then fastened to the camper with VRB tape and #8 screws. I'll leave the panels about 2" clearance from the cab of the truck to prevent any interference problem due to either movement of the camper or flexing of the truck.

Wind Deflector

I'm going to put a wind deflector on the truck overhang of our Host Mammoth. Does anyone know if it is a Azdel of luan panel? Do I need to predrill the fiberglass oversize to prevent the fiberglass panel cracking? I'm using panels of fiberglass about 1/8" thick that I laid up as not a lot of plastic sheeting is available around here.

RE: Host Mammoth Floor Insulation

Good Point, thank you.

Host Mammoth Floor Insulation

I've noticed that the over the bed floor on a Host Mammoth gets really cold in the winter. Has anyone added some foam insulation to the bottom of the floor that extend out from the basement? It looks like it can take about 1", glue and some screws with fender washers would probably be required.
