The Ultra-SR VW Transporter Campervan Conversion
The Ultra-SR conversion by All Seasons Leisure is designed for travellers who want maximum freedom, modern convenience and a premium finish, all wrapped up in a VW T7 campervan that’s ready for adventure in every season.
Built around a powerful lithium electrical system, a zero gas kitchen and smart integrated tech, the Ultra-SR lets you park up further, stay longer and travel with total confidence, whether you’re heading for the coast, the mountains or a quiet wild camping spot. The Ultra-SR features everything from our Ultra-S conversion plus all the features listed below.
Full Off-Grid Power System
The Ultra-SR is built around a 230Ah lithium battery with its own BMS, Bluetooth connectivity and a built-in heater to protect performance during winter touring. Paired with a 3,000W Victron inverter, plus app and touchscreen monitoring, it supports up to 7 days off-grid and lets you run the microwave, 3-pin sockets and induction hob together.
Hot Water and Rear Shower
We’ve developed our own 240V hot water system that links directly to your mixing tap and rear detachable shower head, powered through the inverter so you can use it anywhere in the world. That means proper hot water on the go without campsites, perfect for rinsing muddy boots, washing the dog, cleaning bikes, or sorting sandy kids after a beach day.
Zero Gas Induction Kitchen
Inside the Ultra-SR you’ll find our ZERO Gas setup for added safety, simplicity and a cleaner, modern interior. The large dual-burner induction hob delivers fast, precise heat with smart cooking controls and presets for everything from a quick brew to a family meal. Powered from the lithium system, it keeps the van free from gas bottles.
High Output Solar Charging
Every Ultra-SR comes equipped with a 250W semi-flexible solar panel and the correct charge management system to keep your lithium battery charging 24/7, even while you’re on the move. It’s the largest solar panel we’ve fitted to a campervan, helping reduce reliance on hook up and generators so you can stay off-grid for longer.
Smart Pop-Up Charging Hub
Mounted into the Corian worktop, the Ultra-SR includes an electronically controlled pop-up wireless charger that rises at the press of a single button. It’s also a full charging hub with 2x 240V sockets and USB connections, plus a built-in Bluetooth speaker, ideal for rear passengers while travelling or for music when you’re parked up.
Reimo TUV-Approved Pop Top Roof
The Ultra-SR features the Reimo easy-fit pop top roof, fully TUV approved and crash tested for added reassurance. It’s smooth to operate and secured with a double latch safety mechanism, helping prevent nasty surprises on the road. With trusted Reimo engineering overhead, you can tour with confidence and enjoy extra space and comfort.
