Executive Summary

The CosyRoad 170" from Coastline Vans offers a premium, pre-engineered, turn-key vanlife solution that significantly outclasses the fragmented, risky, and often chaotic process of building a custom Sprinter van. While the appeal of building your own camper van lies in personalization and cost control, in practice, most custom builds suffer from delays, compatibility issues, cost overruns, and unreliable results. CosyRoad 170" eliminates those pain points by delivering a luxurious, fully integrated living experience with cutting-edge features, professional-grade systems, and a seamless aesthetic—all backed by a trusted brand.

Comparing with Custom Build Options

1. DIY Builds

Estimated Cost: $15,000 - $50,000 (excluding van)

Time to Build: 3 to 12+ months (part-time or full-time) unknown or difficult to estimate timeline due to other life commitments, DIY projects are often put to the wayside/stopped and restarted over time.

Pain Points:

Skill Gaps: Most builders lack electrical/plumbing experience
Component Chaos: Sourcing parts from multiple vendors leads to compatibility issues
(e.g., mismatched voltages, plumbing fittings, or cabinet dimensions)
Design Rework: Trial and error is the norm; layouts often require revision
Safety Risks: Poorly installed electrical and gas systems are hazards
Resale Uncertainty: No warranty, no brand recognition = lower resale value
Equipment Uncertainty: Many components do not come with complete instructions, and it is up to the DIYer to do prior research before the install. DIY installs do not come with warranties and are up to the builder to get different brand parts to work seamlessly

2. Kit-Based Semi-DIY Builds

Estimated Cost: $50,000 - $80,000 (kit + appliances + van)

Time to Build: 2 to 4 months Estimated

Pain Points:

Modularity = Limitations: Kit layouts may not fit your van precisely
Assembly Complexity: Still requires electrical, plumbing, and insulation
Fragmented Systems: Battery, solar, appliances often sourced from different vendors
with different specs and support
Limited Support: Most kits don’t include real-time tech assistance or warranties on integration

3. Professional Custom Conversions

Estimated Cost: $120,000 - $250,000+ {Van Not Included}

Time to Build: 6 to 12+ months

Pain Points:

Backlogs: Many boutique builders are booked out a year or more
Hidden Costs: Add-ons and upgrades quickly inflate price and project timeline
Part Compatibility: Even pros sometimes struggle when mixing third-party systems
Build Quality Varies: Smaller builders lack the economies of scale or QC standards

The Hidden Problem: System Compatibility

Custom builds often fail at the intersection of parts and integration. Solar panels from one vendor might not work efficiently with a battery system from another. Diesel heaters can interfere with water lines. Mounting a third-party AC unit may require cutting custom roof holes, risking leaks. Even cabinetry dimensions can conflict with wheel wells or window placements. CosyRoad solves all of this by designing every component to fit together as a single, harmonious system. Electrical, water, and HVAC systems are professionally installed and tested. No guesswork, no trial-and-error.

CosyRoad Is the Smarter Choice

For adventurers who want the freedom of vanlife without the headaches of design, logistics, or construction, the CosyRoad 170" is unmatched. It blends luxury, functionality, and dependability into one pre-configured package. Instead of juggling incompatible parts and praying everything works, CosyRoad customers enjoy peace of mind, professional craftsmanship, and a head-turning van that’s ready to explore the world.
