Geo Metro Truck?

[Christ]

I've read that there is a reasonable aspect ratio between the width and length of the "T" in reverse trikes that should be something like .75:1 (longer than wide), but I don't recall the reference.. I read it "en passant", and it may have been entirely false. Seems logical, though... if you've got a 75 inch front track, a 100 inch separation between the front and rear axle centers seems proper.

I would be inclined to think there's just more to it than that, though... such as center of gravity, etc.

If I had a Metro truck, I would go all out on it............

Stacks (Tri-Stacks?)
Running boards
Bed rails
Dual whip CB antennas
Grille Gaurd
KC Hi lights

Yeeehaw!

So what would you do with a Caravan? LOL. Friend wants to put it on a Blazer frame and rock 33's!

Man, rednecks...

I just wondered, cuz ya know... drive tires and all...

I've heard of High Schools Students that have 'pickup' modded the Geo B4, so we know it can be done - and the eBay pic Proves it - and - hey it's a mod that (probably) saves on weight! So - that's better at slow speeds - less weight to accelerate = more eco friendly - hence - here we are on 'ecomodder'!.

It the AeroCap was made lighter weight than the stock - I am betting your aero would be better, and your weight penalty would be small over the current (pictured) style of pickup mod. You could make it wiith foam - like mine essentially - then fibreglass it using epoxy resins, and then - just disolve out the foam with some old Gasoline!

RR doesn't change unless you swap in different tires, only the power needed to roll it due to whatever drop in weight. Technically, there may be a drop due to having three bearings instead of four, but I don't think it would be measurable.

I don't think that's right... the tire's RR is measured at a specific load rating, but it doesn't always apply to all situations. If you load a tire less, it will have less rolling resistance. We've already proven this by overinflating tires, or removing weight from vehicles, and recording coast-down times.

I believe RR tests are done at max pressure and max load, but I don't recall specifically... seems I forget more about this stuff than I learn lately.
