Van Furniture Kit | Ram ProMaster 136 | Campervan DIY


Description

The TNTvans Ram ProMaster 136 Campervan Conversion Kit is a complete, modular DIY interior solution built for van lifers, weekend adventurers, and anyone ready to hit the road without a full-scale custom build. This all-in-one kit includes a removable van bed with adjustable height, a sliding ice chest with countertop, and a fully self-contained wireless sink system - everything you need to camp comfortably this weekend. Engineered with proprietary 6063 aluminum framework and USA-made cabinet-grade Baltic Birch plywood, the system is dramatically lighter and more durable than traditional wood-jointed van builds.

Unlike bulky wood interiors that warp, crack, and loosen over rough terrain, TNTvans' all-metal bolted framework is engineered to handle off-road conditions without coming apart. Every unit is modular and removable, so your ProMaster 136 can still haul kayaks, mountain bikes, or dog crates when you need it to. Manufactured and shipped from St. George, UT, this kit ships free to the contiguous United States and is designed to be assembled at home with minimal tools and full customer support.


Key Features

  • Proprietary 6063 Aluminum Framework: Lightweight and strong - no wooden joints, no screws that loosen on off-road trails.
  • USA-Made Baltic Birch Plywood: Cabinet-grade panels with a clear semi-gloss epoxy acrylate finish and four-coat UV coating. SEFA 8.0 certified.
  • 4 Adjustable Bed Heights (19", 30", 40", 51"): Choose the clearance and under-bed storage that fits your lifestyle; raise it later with Stack-On Shelving.
  • Removable Bed Platform: Unbolts from the floor to open a large center aisle for hauling oversized gear - kayaks, bikes, crates, and more.
  • Van Ice Chest Slide & Countertop: Locking sliding tray designed around the ICECO 45L; elevated off the floor to create bonus storage underneath for shoes and camping gear.
  • Wireless, Self-Contained Sink System: Includes sink, hoses, fittings, manual water pump, and two water tanks - no plumbing or wiring required.
  • Modular Stacking Shelving: Base section is 18" tall; each bin shelf adds 11". Units can be stacked in any order and reconfigured at any time.
  • T-Slot Attachment Points: T-slots forged into the metal framework let you strap gear down at any point along the structure.
  • Kit Weight Under 86 lbs (at 19" bed height): Full camper system stays well under 200 lbs - no overload springs needed on your van's suspension.
  • Assembly & Install Time - ~12 Hours Total: Assembly estimated at 8 hours, van installation at 4 hours, with full step-by-step picture instructions and personal support included.

Bed Height Options & Which to Choose

  • 19" Bed Height: The lowest profile option at 62 lbs with 17" of clearance beneath the platform. Best for those who prioritize a lower center of gravity, easy entry, or don't need substantial under-bed storage.
  • 30" Bed Height (+$558): A popular middle-ground at 70 lbs with 28" of clearance - enough room for a full row of shelving underneath and comfortable standing access to stored gear. Great for most weekend campers.
  • 40" Bed Height (+$1,116): At 78 lbs with 38" of clearance, this option opens up serious under-bed storage and is ideal for gear-heavy adventurers who want bins, batteries, or bulky equipment stored below.
  • 51" Bed Height (+$1,673): The tallest option at 86 lbs with 49" of clearance - maximum storage capacity underneath. Perfect for full-time van dwellers or those converting to a dedicated mobile workspace who need every inch of storage they can get.

What's Included

  • (1) Van Bed 48" & Shelving Kit - 2 Platform with HDEVA Foam spacers for a level sleeping surface
  • (1) Van Ice Chest Slide & Countertop (locking sliding tray designed around the ICECO 45L)
  • (1) Van Sink System - includes sink, hoses, fittings, manual water pump, and two water tanks
  • All mounting hardware (riv nuts for metal floors or wood inserts for wood/composite floors, based on selection)
  • Step-by-step assembly instructions with large pictures

Why You'll Love It

TNTvans has built a reputation among DIY van converters for delivering a system that's genuinely engineered - not just assembled from wood and screws. The all-aluminum framework and modular bolt-together design means your Ram ProMaster 136 interior can survive weekend trail runs without rattling loose, and it can be removed and reinstalled whenever your needs change. Every kit is manufactured right here in the USA in St. George, UT, so quality control is tight and lead times are short. You get free shipping to the lower 48, and unlike most van furniture kits, you also get direct personal support - the builder's own cell phone number - to help you through every step of assembly and installation. Whether you're converting your first van or upgrading from a basic build, this kit gives you a functional, professional-looking campervan interior without the $20,000+ price tag of a full custom conversion. It's trusted by builders from all walks of life, including aerospace engineers who know quality when they see it.

FAQ

Does this kit fit the Ram ProMaster 136 specifically, or other ProMaster sizes too?

This kit is designed and sized specifically for the Ram ProMaster 136-inch wheelbase model. TNTvans does offer kits for other van models and sizes, but you should select the correct kit for your exact van to ensure proper fitment. If you're unsure, reach out to TNTvans directly for guidance before ordering.

Do I need any special tools to assemble and install this kit?

Very few tools are needed. The main installation requirement depends on your van's floor type: if you have a metal floor, you'll need a riv nut installation tool to install the provided riv nut anchors. If your van has a wood or composite floor, wood inserts are included. Beyond that, basic hand tools are sufficient. TNTvans provides step-by-step picture instructions and personal customer support via phone, email, text, or FaceTime throughout your build.

Can I remove the furniture if I need to haul cargo or sell the van?

Yes - the entire system is designed to be removable. The bed platform and all units bolt to the floor and can be unbolted and taken out when you need to use your van for hauling large items like kayaks, mountain bikes, or dog crates. This is one of the core design advantages of the TNTvans system versus permanent custom builds.

What ice chest brands will fit the sliding tray?

The ice chest slide is designed around the ICECO 45L, but it can accommodate many brands of ice chests of similar size. If you're using a different brand or size, it's recommended to confirm dimensions with TNTvans before ordering to make sure it will fit properly in the slide tray.

Is the sink system truly wireless - do I need to do any plumbing or electrical work?

Yes, the Van Sink System is fully self-contained and wireless. It uses a manual water pump, so there is no electrical wiring required and no connection to an external water source. It comes complete with the sink, hoses, fittings, and two water tanks - just install it and you're ready to go.

Can I add shelving or modify the kit later if my needs change?

Absolutely. The TNTvans system is fully modular. You can purchase Stack-On Shelving at any time to add more storage levels or raise your bed height. Doors, drawers, side panels, LED lighting, and MOLLE panels are all available separately through the accessories menu. The system is designed to grow with your build over time.

Is local or in-home installation available if I don't want to do it myself?

Yes. If you'd prefer not to install the kit yourself, TNTvans offers local installation at their facility in St. George, UT. They also offer a VIP "In Your Driveway" installation service for customers who want professional installation at their own home. Contact TNTvans directly for scheduling and pricing details.
