How much does this Sprinter conversion cost?
A new AWD Sprinter conversion – such as this Beyond4 build – from Crozier Campers starts at £134,500. This particular build features some premium upgrades, including the Dometic air conditioning and the Advanced Electrical System. Please download the Beyond4 Pricing and Specification sheet for more info.
For a used chassis Mercedes-Benz approved Sprinter (RWD), prices start from £88,225 (all prices include VAT).
Why is the Mercedes Sprinter so popular for conversions?
The Mercedes Sprinter, as a panel van, is a cornerstone of the conversion market for good reason.
It offers an unparalleled Mercedes-Benz user experience with car-like driving dynamics, reliability, and an abundance of advanced safety features. It’s truly a van you can trust.
That’s why the Beyond4 is exclusively available on the Sprinter chassis; its quality and versatility provide the ideal foundation for a premium conversion.
Can the Dometic air conditioning be run off-grid in a Mercedes Sprinter camper van?
Absolutely.
The Beyond4 features Crozier Campers‘ ‘Advanced Electrical System’ premium upgrade, specifically designed to power the Dometic RTX2000 12V air conditioning system.
This powerful setup, with its substantial lithium battery bank and solar array, allows for extended cooling even when far from hookups.
Is the all-wheel drive (AWD) the same as a 4×4 Sprinter van?
Not exactly.
Mercedes-Benz Sprinter vans are now equipped with an advanced All-Wheel Drive (AWD) system, which differs from the previous traditional 4×4 camper.
The AWD provides enhanced traction and stability on varied surfaces like gravel, mud, or snow, making it highly capable for most adventurous routes, but it’s typically a permanent system without the low-range gearing found in dedicated off-road 4x4s.
What are the key advantages of the Beyond4’s fixed bed layout?
The fixed bed layout liberates significant space for a full-width garage beneath, perfect for storing bikes and large adventure gear.
It also provides a dedicated, comfortable sleeping area, eliminating the need to convert seating areas nightly. However, if you love the thought of an extra spacious lounge, check-out Beyond2 – a LWB Sprinter campervan with U-shaped lounge and cinema.
Is the Beyond4 an overland motorhome – designed for serious adventure and gear transport?
Definitely.
Its expansive rear garage, accessible from the interior, is built to accommodate substantial gear. Combined with ample interior storage solutions like the dedicated wardrobe and elasticated shelving, the Beyond4 is engineered for active lifestyles and extended trips with all your essentials.
