Hi Mbasaraba/Matthew & Tammy,
Welcome to the forum !
Nice van you've done up there. I remember riding in a similar
one way back in H.S. on a couple school trips.
I know you said you are just starting out, but do you have a direction
that your design will take ? One approach could be to do a take-off
on your van, similar to what the Dub-Box is for the VW van.
http://www.dub-box.com/ .
This Foamie section thread has some aero info collected in it that may
be beneficial.
http://tnttt.com/viewtopic.php?f=55&t=49036 . Sizing the TTT
to the tow vehicle could be very apropos possibly.
If you are bending frame/chassis parts, are you thinking of using steel tube
[1x1 e.g.] for the body framing as well ? If you bend the frame/chassis with
the 6.5in radius, that could be carried up in the body wall-corner which
would be very beneficial aero-wise.
Another question - If you go the Dub-Box like route, can you get the front Van
section of the Chevy vans like yours ? Using those as the front and rear walls
of a slouchy TTT might be an interesting look - sort of like those trailers you
see made from the same sheet metal pieces as their tow vehicles.
Have fun researching and designing, then building.
Cheers,
Norm/mezmo
P.S. It might be a good idea to do a short intro in the newbies section with a link
to this, your Build Journal thread. You'd get more exposure and that'd probably
result in more answers to questions you may have and such.
If you have a house - you have a hobby.
