2 Ton BIG A KM-4000T TEPX Propane Trailer Hot Asphalt Hauler

What are the differences?
Aside from the normal obvious differences between our Propane models and Diesel models, we get this question a lot.

The biggest difference between the Propane and Diesel versions is the way the heating system works.  Obviously, one is propane and the other is diesel, but how the fueling is controlled between the two, is where they differ.

Propane
The propane version has a static thermostat where you set the dial and walk away.  It's easy to use and there's not much to think about, but that's pretty much as far as it goes.  You can't setup custom time schedules or program the propane version.

Diesel
With the Diesel version, it has what we call a "Smart Thermostat" which has an actual programming logic controller and this lets the system control heating to be even more efficient, saving you money in fuel costs.  The diesel version also has data logging, which let's you take a look at how well the system is heating to know if your hot box is working at peak efficiency.  In addition, the smart thermostat will let you control heating requirements, allowing you to literally walk away and forget about it, or you can setup a time schedule and have the burner turn on or off at pre-determined times.  For example, set it to turn off over the weekend and automatically turn on for the week.

Conclusion
Better tools means a higher cost, so if you're looking at a budget system that's easier to use, the propane is probably the best bet.  But if you want to know exactly where your money is going, and you want a system with the highest heating efficiency, diesel is the way to go.

The Big A 2-Ton Asphalt Trailer Hauler holds up to 2 tons (4000 lbs) of milled or recycled hot asphalt and features a 58,000 BTU BTU propane burner for fast and efficient material heating and the key components are mounted above the frame and in a steel enclosure protecting them from the weather. Fuel is supplied by two propane cylinders (not included) conveniently located on the trailer's front allowing for easy cylinder change-out. 30lb propane cylinders are recommended as the minimum LP bottle size but this can easily handle dual 60lb or 100lb bottles.

A single top mounted cantilevered shock assist filling door makes it easy to open and close and only requires 15 pounds of pressure to operate while standing on the ground, and this trailer utilizes a single insulated 10″W x 16″H sliding shoveling door with track design. Asphalt is fed from a gravity feed slanted wall funnel design for easy discharge to shoveling door and making it easy to reach the material with a shovel.
