With the number of deer around here I really should get a nudge bar... I've been trying to reduce the number of things I stick on the outside of the van due to aerodynamic drag = reduced mpg.

General consensus seems to be that a roof rack alone on a Sprinter costs it about 2mpg

Connectors = 8020 versatility?

standard t-slot nut. allows you to slide whatever you are fastening to it anywhere along the channel that you like



"roll-in" t-slot nut with spring-loaded ball. If you have your assembly all together and want to add something later without taking it apart.. these guys roll into the channel without needing an end to slide in



these guys are the opposite.. giving you a stud anywhere along the channel you want to attach an item:





These guys are the strongest corner anchor 8020 makes. They do require some drilling/machining to countersink. I'll be using these on the main corner intersections of the bed to make sure it is strong enough.




These other connectors are ones I've shown before - I'll be using them for various intersections:



I actually bent one of these $9 jobbies





with all of these connectors.. bolt lengths become pretty important. You need bolts that go in far enough to fasten securely but not so far that they bottom out in the t-slot.

That's about right on my S320 too. Add bicycles and it gets much worse.

For example: trip from NoVA to Denver... Set the cruising control at 74mph and went toodling down the road. Got 24mpg

On the trip back from Denver to Nova, I had 3 bikes and an extra pair of wheels on the top. Set the cruising control at 65mph and got 20-ish mpg

Yeap, hitch racks rule for gas mileage and reduced wind noise.

Is it bad when 3 people who work at Home Depot have gotten to know you buy name... and you get asked "how's the van build going?" when you walk in?

I can't believe he hasn't grown out of that yet! We have to lock Malo in the back room at night, or we'd never get any sleep. He's 9 yrs old, so maybe some cats just never grow out of that!

Ed, forgive me if I'm over-thinking (or even more likely under-thinking), but you are taking into account the natural expansion and contraction of wood with changes in temperature and humidity, right?

I can just see a now-perfectly-sized plank shrinking and pulling out of the slot(s) or expanding and buckling or causing mount deformation.

I am an ignoramus when it comes to the material properties of wood. We didn't really study it much in college materials science class.

instant chemical bomb goes off the moment your turning tool hits the chunk as the sap / liquid sprays everywhere and shuts down your lungs.

Maybe that was their "inside joke".

I have.. and I'm leaving more than the prescribed amount of expansion space.
I think they said something like a 1/4" of expansion over a 22 foot room...
