The Three Dominant Platforms

The vast majority of professional campervan conversions in the UK are built on one of three van platforms: the **VW T6/T6.1**, the **Mercedes Sprinter**, or the **Ford Transit**. Each has a genuinely different character, price point, and conversion suitability — the right choice depends on how you intend to use the finished vehicle.

This guide uses real UK dimensions and market prices. Conversion costs on top of the base vehicle are not included here — see our separate costs guide for that breakdown.

VW T6.1 (2019–present)

The T6.1 is the aspirational choice. It dominates the mid-range conversion market and commands strong resale values.

**Dimensions (SWB):** 4,895mm long × 1,904mm wide × 1,990mm tall (standard roof)

**Dimensions (LWB):** 5,299mm long

The critical internal measurement for conversions is the width between the rear wheel arches: approximately **1,380mm**. This is noticeably narrower than the Sprinter or Transit and limits bed width — a fixed double typically requires creative joinery or a slightly narrower mattress than you might expect.

**Internal load length:** 2.8m (SWB), 3.2m (LWB)

**Engine:** 2.0 TDI diesel in multiple outputs from 84bhp to 198bhp. The 150bhp variant is the most popular for conversions.

**Purchase prices (UK market, 2026):**

  • New: £32,000–£45,000 depending on trim and spec
  • Used (approximately 3 years old): £22,000–£35,000

    • **Pros:**

  • Excellent build quality and driving refinement — genuinely car-like to drive
  • Exceptional resale value — retains value better than any rival
  • Enormous aftermarket ecosystem for accessories and parts
  • Large network of specialist T6 converters with proven designs
  • Premium image — fits easily in urban environments and car parks

    • **Cons:**

  • The most expensive base vehicle of the three
  • Narrow between wheel arches constrains interior width
  • Smaller total volume means no room for a proper bathroom in SWB
  • Standard roof height (approximately 1.96m internal) requires a pop-top or high-top for comfortable standing

    • **Best for:** Couples or solo travellers doing weekend trips to 2-week holidays. People who drive the van daily and want something refined and city-friendly. Those who want strong resale value.

    Mercedes Sprinter (L2H2 most popular)

    The Sprinter is the workhorse of the professional conversion market, especially for builds requiring a bathroom or serious off-grid capability.

    **Available lengths:** L1 (5,910mm), L2 (6,360mm), L3 (6,910mm)

    **Available heights:** H1 (standard), H2 (high roof), H3 (extra-high)

    **Internal dimensions (L2H2 — most popular for conversions):**

  • Length: 3,720mm
  • Width: 1,765mm
  • Height: approximately 1,850mm (H2 high roof adds ~300mm over H1)

    • The Sprinter's internal width is significantly more generous than the T6 — a proper 2,000mm-wide mattress is achievable. The H2 high roof provides genuine standing height without any aftermarket modification.

    **Engine:** 2.0 CDI diesel (114–177bhp). The 170bhp variant suits the larger, heavier builds.

    **Purchase prices (UK market, 2026):**

  • New: £38,000–£55,000
  • Used (approximately 3 years old): £20,000–£32,000

    • **Pros:**

  • Significantly more interior space than the T6 — room for a bathroom, proper kitchen, and bedroom as separate zones
  • H2 and H3 roofs give standing height from the factory
  • Good motorway cruising ability for long journeys
  • Multiple converter ecosystem; many specialist Sprinter builders in the UK
  • Strong reliability record (post-2014 models; early AdBlue issues are largely resolved)

    • **Cons:**

  • Noticeably large in urban environments — parking in cities requires planning
  • Less refined to drive than a T6; feels more commercial
  • Older models had issues with the AdBlue dosing system — check service history carefully on used examples
  • New prices are high; the value is usually in the used market

    • **Best for:** Couples or families wanting a bathroom. Full-time or extended travel (weeks to months). People prioritising interior space and off-grid capability over driving character or image.

    Ford Transit (L2H2 most popular)

    The Transit is the value proposition of the three. Its internal dimensions are competitive with the Sprinter, but it undercuts on purchase price, insurance, and running costs.

    **Available lengths:** L2 (5,531mm), L3 (6,068mm)

    **Available heights:** H2 (high roof) most popular for conversions

    **Internal dimensions (L2H2):**

  • Length: 3,760mm
  • Width: 1,786mm
  • Height: approximately 1,830mm

    • These dimensions are directly comparable to the Sprinter L2H2 — the Transit is fractionally wider internally and similar in length.

    **Engine:** 2.0 EcoBlue diesel (105–185bhp). Widely regarded as one of the most fuel-efficient and reliable engines in the large panel van segment.

    **Purchase prices (UK market, 2026):**

  • New: £34,000–£45,000
  • Used (approximately 3 years old): £18,000–£28,000

    • **Pros:**

  • Cheapest of the three to buy new and used
  • Very competitive internal dimensions versus the Sprinter
  • Excellent fuel economy — the 2.0 EcoBlue is genuinely efficient
  • Massive Ford dealer network for servicing — competitive servicing costs anywhere in the UK
  • Lower insurance costs than a T6 or Sprinter

    • **Cons:**

  • Less premium image than the T6 or Sprinter — this matters to some buyers, not others
  • Lower resale value than a T6
  • Fewer specialist converters than T6 or Sprinter, though this is changing rapidly as Transit conversions grow in popularity
  • Fewer dedicated aftermarket accessories than the T6

    • **Best for:** Value-conscious buyers who want Sprinter-comparable space at a lower price. Those doing high UK mileage who want low running costs. Families who don't place a premium on the badge.

    Other Platforms Worth Knowing

    **Peugeot Boxer / Fiat Ducato / Citroën Relay** — all built on the same platform. Significantly cheaper than a Sprinter or Crafter new, with a generous internal volume. Particularly popular among budget-to-mid conversions where space is prioritised over prestige. Less desirable on the used market but outstanding value for money.

    **Vauxhall Vivaro / Renault Trafic** — similar footprint to the VW T6 at a considerably lower price. A growing number of converters offer Vivaro-based builds as an alternative to the T6 for buyers who want the compact format without the premium cost.

    Summary Comparison

  • **Choose the T6.1 if:** You want the best driving experience, strongest resale value, and are happy with the compact footprint. Budget for a premium.
  • **Choose the Sprinter if:** You need a bathroom, want standing height without modification, or are planning extended or full-time travel. The space justifies the size.
  • **Choose the Transit if:** You want Sprinter-comparable space at a lower purchase and running cost, and you're not attached to the badge.
