Research-based shortlist, not a verified-fit list. Confirm your model year, body style, trim and seat layout before buying.
This guide builds on our general guide to choosing the best kennel for your vehicle. Start there for the overall approach, or change vehicles with the selector below.
Start with your Ram ProMaster’s layout
A ProMaster can offer useful space for dog transport, but the badge covers different lengths, roof heights and interior builds. Start with the actual van: an empty cargo shell, a work van with shelving and a camper conversion are three different kennel projects. Record the wheelbase, roof configuration and permanent equipment before choosing a layout.
Choose the loading route before placing the kennel on a floor plan. Rear access and sliding-door access can each work differently once cabinets, seats or a bulkhead are installed. Include the space needed for a person to operate every kennel latch and for a dog to enter without crossing loose equipment. A large total cargo-volume figure does not describe these everyday movements.
An upfitted ProMaster needs an installation plan that treats people, dogs and cargo together. Ask the upfitter about appropriate attachment locations, floor construction, ventilation and temperature control in the area where the dogs travel. Do not rely on empty space or a decorative floor panel as structural evidence. Keep emergency access and everyday cleaning in the design, and test the completed layout with the van packed for its normal job.
The checks that matter here
- Wheelbase, roof height and installed conversion equipment
- Rear versus sliding-door loading route
- Upfitter-approved installation and climate-controlled dog space
Kennels we would compare for the Ram ProMaster
For a removable setup, compare individual Gunner G1 and RuffLand kennels sized for each dog, with installation instructions checked against the proposed van arrangement. A double-door RuffLand can be useful when it connects a rear-loading route with a usable internal aisle. We would not assume that a second door improves access if an adjacent cabinet prevents it from opening.
RuffLand single-door kennel
A removable rear-loading candidate for a ProMaster when shelving and work equipment leave a direct, unobstructed route to the kennel door.
When we would pass: A decorative conversion floor is not evidence of structural support or appropriate attachment beneath the kennel.
Check this option and its instructions →
Gunner G1
Compare as part of the ProMaster conversion plan, including the actual floor, partition, ventilation and instructed securing arrangement.
When we would pass: A cabinet next to the second door can eliminate its benefit; test the finished upfit, not the empty van shell.
Check this option and its instructions →
RuffLand front-and-back double-door kennel
Worth investigating when a ProMaster layout provides both a rear loading route and a clear internal aisle to the opposite door.
When we would pass: Both doors need genuine operating clearance; adjacent cabinets, stacked equipment or a partition can erase the access benefit. Choose the interior size for the dog first.

These are candidates to investigate, not confirmed fits. Match the exact size and installation instructions to your dog and vehicle before ordering.
Before you order
Use the main guide’s dog-sizing and loading-route checklist to test your chosen layout. Review how to check crash-test evidence for the exact product and installation; a successful physical fit does not establish crash protection.
Bring your dog’s measurements, your model year and trim, and photos of the intended installation area to the kennel seller. Ask for the exterior envelope and usable interior measurements of the exact size and door configuration. Confirm the return terms before a trial fit.
