Frequently
Asked
Questions
-
The TrailBlaze plate is designed to fit any gasoline air heater that is compatible with the Ram ProMaster.
We have tested the plate with the gasoline heaters used throughout the van-build market, including major brands and common aftermarket heaters. -
Most installations take approximately 1–3 hours, depending on your experience with tools and van building. The plate is designed to be added as one step within your normal gasoline heater installation.
-
Without a purpose-built mounting solution, figuring out how to properly fit a gasoline heater under the ProMaster passenger seat can easily turn into 3+ hours of trial and error, fabrication, and problem solving.
The TrailBlaze plate eliminates that guesswork and gives you a purpose-built mounting position from the start. -
No. The TrailBlaze kit includes the mounting plate and pre-installed sealing ring. It is not a complete heater installation kit.
You will still need the heater and the tools, hardware, fuel-system components, wiring, exhaust, intake, and other components normally required to install your specific heater.
-
The TrailBlaze plate does not require modifications beyond what is normally needed to install a gasoline heater in this location. You will need to create the appropriate opening in the floor for the heater components.
-
We recommend a 4.5–5 inch opening. A smaller opening can make it difficult to route and position the exhaust and fuel line. Going significantly larger can increase the risk of cutting into components beneath the floor, so we recommend staying within the 4.5–5 inch range.
-
Yes. The installation is designed to be DIY-friendly for someone comfortable with basic mechanical work, tools, and van building. We provide a detailed installation video and written installation guide specifically for installing the TrailBlaze plate.
-
For questions specifically about the TrailBlaze plate, mounting the heater to the plate, positioning the plate, or routing components through the plate, contact us and we'll be happy to help.
For the rest of your heater installation, we recommend following the instructions supplied with your heater and using an installation guide specific to your heater model. -
Yes. If the gasoline air heater is compatible with the Ram ProMaster, it is compatible with the TrailBlaze mounting plate.
