Here is a carefully curated selection of my techs. Some were made during the campaign, others for fun.
~Light Venture stunt car "Little Speedster"~

A small, compact vehicle designed for racing and stunts. While it lacks the speed to jump through extremely high hoops or drag race against the greatest techs, it can complete most tracks with time to spare. Useless in combat, except possibly as a distraction or escape vehicle.
The first prototype was built by Suzie Vroom. Venture recruits quickly began copying her design, at which point she switched to her weird upright tech just to mess with them. The lack of weapons made it all to easy for rogue prospectors to prey on Venture recruits, so poor Suzie had to start handing out free Avalanche launchers. Which made Venture recruits an even more popular target, because everyone wants an Avvlanche launcher.
Speed: Very fast.
Agility: Can climb pretty much anything and turn on a sixpence.
Size: Tiny.
Weight: Very light.
Armament: Maybe you could ram something?
Defences: Brittle carbon fibre armour. The suspension can cope with a few long falls, though.
Special Abilities: Powerful rocket boost, long-range radar, front-mounted landing gear to help with mounting ramps.
Weaknesses: Exposed cab, no weapons, exposed fuel tank.
~Long-range destruction platform "Amazonian Mortar"~
A Megaton cannon platform designed to attack enemies at range and/or in hard-to-reach places, easily built from blocks you can acquire by beating up a late-game enemies. The front armament can take care of enemies who manage to get closer, but it doesn't have the shielding or the manoeuvreability for long fights. It can cope with ice and rough terrain and use hills to fine-tune its firing angle. One volley can turn any enemy into a pile of blocks, unless it's properly shielded and covered in armour. In that case, two or three volleys should do it.
Only a few Amazonian Mortars are currently in service, but any prospector who owns one is guaranteed to get some slack from pirates and tax collectors, and customization is easy. All the major companies have at least one Amazonian Mortar or their own version on hand at their base.
Speed: Slowish.
Agility: Can climb fairly steep inclines and turn in place.
Size: Large-ish.
Weight: Quite heavy.
Armament: Nineteen Megaton cannons angled to fire in a long arc. Ten three-pound cannons and ten eight-barrel mini-mortars for point defence.
Defences: Strong metal bodywork.
Special Abilities: Shoots explosive shells in a long arc. I mean, isn't that enough?
Weaknesses: Exposed cab.
~Venture Hybrid Heavy Assault Truck "Liberator"~

Made after some Venture pilots struck a deal with Hawkeye, the Liberator is a powerful long-range combat vehicle at home in difficult environments. The three HG-1 cannon turrets have enough power to take out most enemies, while the front-mounted contact shotguns and Oozee SMGs can tear through shields. The batteries and fuel tanks are protected by several repair bubbles.
The Liberator is well-known by privateers operating near Team Venture's main base. Most of them have been chased down at least once. Independent Venture license-holders see the Liberator as a symbol of hope, and have shamelessly copied its design countless times.
Speed: Fairly fast.
Agility: Can climb hills and do wheelies. Turning circle isn't too great.
Size: Medium-large.
Weight: Medium.
Armament: Three HG-1 heavy cannon turrets, three Avalanche missile launchers, several guns.
Defences: Shielding covers the entire hull. Strengthened carbon fibre plating with aggregated carbon nano-rod armour over the fragile, explosive components.
Special Abilities: Powerful booster rockets.
Weaknesses: A Megaton volley will generally be enough to blow it up. Getting it to stay still for long enough is difficult, though.
