Reality checking my work, the side armor an M8 Greyhound was supposed to stop 7.62mm bullets, and a Greyhound's side armor is 9.5mm thick <https://en.wikipedia.org/wiki/M8_Greyhound>.

Re: [AtE] Wasteland vehicle improvised weaponry
I did some very quick calculations for an entry in another thread.
1/4 inch steel plate adds 6.7 tonnes for a large truck, I worked off a lightly lower DR per inch than Mslangdorf and eyeballed the DR per inch at 60, making a plate covered battletruck DR 15. High power air rifles (based on a current real world model) come in at about 2D+2 with a .50 caliber slug.

You will need to do some research to determine the ballistic efficiency of boiler plate to steel armor (it is lower, possibly .45)) and the typical thickness range of the plate.

If you want to armor the hood and and doors of the cab, but not the bed, you're looking at 6.7 * 3.5 + 2 * 13 * 3.5 + 5.5 * 6.7 = 151 sqft of armor plate. That 2400+ lbs right there. The windows are 2 * 7.5 * 2 + 6.7 * 3.5 (ish, the front windshield is curved and angled, but you'd want gaps to see through it...) = 60 sqft of armor plate, and another 1000 lbs. The cab roof is about 6.5' by 6.7' feet = 44 sqft and another 700 lbs. The sides and back of the bed are 3.5 * ( 2 * 8 + 6.7 ) = 80 sqft and 1300 lbs. A bed cover is around 60 sqft and another 1000 lbs. So I get a tidy 6400 lbs for 10mm armor everywhere you care about except the underside. You can optimize that a bit, but as copeab points out, you may not be working with good quality armor plate, in which case doubling the weight isn't unreasonable. If you want a battlevan or battle SUV, weight goes up a lot, because now the back of the is 2-3' taller.

Re: [AtE] Wasteland vehicle improvised weaponry
There are some cultural differences at work here, I would call that a Ute, sorry for any confusion. The numbers I played with where for a vehical more suited to being the front unit on a road train.

Re: [AtE] Wasteland vehicle improvised weaponry
You can save a lot of weight by only armoring the important bits. For a pick up truck, I would armor the engine compartment(complete with a cow catcher grille) and the drivers seat. The rest would be a "fighting platform" for my warriors, and it doesn't need a lot of armor. Roll cages are still a generally good idea.

Re: [AtE] Wasteland vehicle improvised weaponry
A lot of low technology is terrifying but not very portable, especially when it's built with scraps of high technology. A truck leaf-spring would make a 40ST crossbow pretty easily but it would be really heavy and cumbersom unless you mounted it to the back of a truck. It would take a long time unless there was a rotor that spun off the axle of the truck that powered it's self-cocking crank. If you were especially good at engineering you could mount 4 of them to a pintle on a vehicle and have someone shooting a ST 40 crossbow bolt each turn while someone loaded the others. A large slingshot takes very little ingenuity or exotic parts, shooting it doesn't take a lot of skill. If you lob a ball of burning tar at the hood of a car it will obstruct vision and smoke out the driver, if you get lucky and land it in the drive's compartment you've started a fire the driver will want to get out of the vehicle for. Hornets nests are also nothing you want stuck in your armored grill. Caltrops, oil slick, paint, nuclear waste..

Re: [AtE] Wasteland vehicle improvised weaponry
A radio controlled/dumb/kamikaze go-kart loaded with improvised explosives would make an erratic but potentially devastating weapon.
