Trailer & Caravan Generator

Trailer & Caravan Generator builds detailed, ready-to-render trailers, caravans and motorhomes in one click, in real-world meters. Pick one of 21 ready-made models: a European touring caravan and a twin-axle tourer, a US travel trailer and a ribbed aluminium one, a riveted polished aluminium classic and its compact sister, a vintage canned ham, a fifth wheel, a teardrop, a squaredrop, a pop-up tent camper, Class A, B and C motorhomes, an alcove camper, a horse trailer, an enclosed cargo trailer, a food trailer, a utility trailer, a car hauler and a boat trailer with its boat.

Then change anything and the trailer rebuilds live: length, width, height, floor height, axles, wheel size and style, hitch, windows, doors, lockers, roof vents, air conditioning, solar panels, awning, colors, graphics and the model name painted on the side.

Every trailer is modeled to be looked at up close: real chassis rails and A-frame drawbar with a hitch head, breakaway cable and jockey wheel, leaf spring or torsion axles with hubs and brake drums, corner steadies, tyres with tread in proper wheel arches, framed windows with rubber seals and real glass thickness, entrance doors with handles, locks and hinges, locker hatches with shut lines, tail light clusters with lenses and reflectors, and painted graphics that never z-fight with the body. Look through the windows and you see a real interior: seating, beds with pillows, a galley with hob and sink, overhead lockers, blinds, stalls for the horse trailer, a stainless kitchen in the food trailer.

Doors, the rear ramp, the galley hatch, the serving flap, wheel spin and motorhome steering are animated through drivers, so they play back in real time without a rebuild.

Installation

In Blender open Edit, Preferences, Get Extensions, then use Install from Disk and pick the trailer_caravan_generator zip.

Usage

• Open the Trailer tab in the 3D viewport sidebar (N). With nothing selected, click the picture to pick one of the 21 trailers, then press New Trailer. You can also use Shift+A, Mesh, Trailer & Caravan.
• The card at the top shows the trailer. Click its picture to switch to another preset. Surprise Me makes a random trailer, Variation changes the current one and New Seed reshuffles the small details.
• The Look box sets the finish, the colors, the side graphics and the model name painted on the side. Open trailers show their deck and load here instead.
• Doors Open, Drive and Steer are animatable sliders. Awning Out rolls out the awning and Lights On makes the tail, marker and interior lights glow.
• The closed sections below hold the details: body and size, running gear, windows and doors, roof and exterior, interior, wear and export.
• For game engines set Detail to Low and use Convert to Mesh; the meshes have UVs, the origin on the ground under the middle of the trailer and plain Principled BSDF materials.

Which Blender versions are supported?

Blender 4.2 and newer. It is tested on Blender 4.2, 4.5 and 5.2 LTS.

Can I use the trailers in a game engine?

Yes. Set Detail to Low, then use Convert to Mesh. The meshes have UVs, the origin on the ground and plain Principled BSDF materials with image textures, so they export to FBX and glTF for Unreal, Unity or Godot. Doors and wheels are separate objects.

Can I see inside?

Yes. Closed trailers have a modeled interior that shows through the windows and the open door: seating, beds, galley, lockers, horse stalls, cargo or a stainless kitchen. Turn Interior off in the Interior section for lighter scenes.

Can I animate the doors and the wheels?

Yes. Doors Open, Drive and Steer are animatable and only move the doors, ramps, hatches and wheels through drivers, so keyframes play back in real time without a rebuild.
