Post apocalypse movie from the 70s or 80s with a truck in it [duplicate]

Question

For years I have been trying to track down a film that I saw a clip of on an old BBC show called Screen Test.

They introduced the film as "having used the most scrap from scrap yards than any other film."

It was either an Australian or a New Zealand film. Post apocalyptic like Mad Max. In-fact for years I thought Mad Max would be the film, but it wasn't.

They showed one scene from the film which the contestants answered questions on.

A six wheel truck drives up to the camera. It looks like a Mad Max truck. There are at least two people in the truck, a man sits close to us with a woman next to him. He looks through binoculars (sci-fi bins). He sees a long trailer thing on rails and it has sails. Then this land ship is attacked by bandits on motorbikes or something. The sails fall and people run about panicking. Then we cut back to the truck and it drives away.

The film is not Battletruck or Damnation Alley. The truck I think had six wheels, but I could be wrong. Not evenly spaced wheels, with the second wheels set back. A gun slung at the back, like a chain gun. It was futuristic like and pointy like a Lambo, not a square truck. In black or dark grey.

Like this but with another set of wheels at the back and painted dark:

It probably wasn't a very good film and has dropped below the radar of obscurity. Anyone who could help ID this film for me would be greatly appreciated.

You can see how obsessed I am as still making models of it in Lego:

Here is a bad drawing of what I remember:

Answer 1

Spacehunter: Adventures in the Forbidden Zone

Answer 2

I know you said it's not Battletruck but I'm reasonably sure you're talking about Battletruck. It was made in New Zealand and is frequently spoken of as a Mad Max clone.

Answer 3

Damnation Alley? First Lieutenant Jake Tanner (Jan-Michael Vincent) shares ICBM silo duty at an American air force missile base in the Californian desert with Major Eugene "Sam" Denton (George Peppard), who is requesting not to work with him. On their way to duty, Denton talks to Airman Tom Keegan (Paul Winfield), an aspiring artist. When the United States detects incoming nuclear missiles from the Soviet Union, Tanner and Denton launch part of the retaliatory strike. The United States is hit hard, although it manages to intercept 40% of Soviet missiles.

Two years later, the Earth has been tilted off its axis by nuclear detonations of World War III; radiation has mutated insect life, the planet is wracked by massive storms, and the sky is in a perpetual aurora borealis-like state. Tanner has resigned his commission and has been scouting Barstow while Keegan, who has also left the Air Force, has been painting as an artist in one of the base's out-buildings. Mutated giant scorpions menace the area. Later an airman falls asleep in a bunk and drops a lit cigarette onto a pile of Playboy magazines, which causes the entire base to catch fire and explode, killing most of its inhabitants including the base commander, General Lander (Murray Hamilton). Keegan and Tanner are unscathed, as are Denton and Lieutenant Tom Perry (Kip Niven), who were in an underground garage bunker.

Answer 4

Ark II TV Series (1976)

"Three young scientists travel around the country in the 25th century after the world has been ravaged by pollution. In their hi-tech RV (called Ark II), they study the land and help out those in need." (IMDB)
