The foot-flushing RV-style restroom trailer from Tow-Let Manufacturing includes urinal, hand-wash sink, soap, towel and tissue dispensers with six-bulb LED solar-powered interior and exterior lighting. Mounted on a DOT trailer, the PolyJohn restroom, available in an assortment of colors, has a 50-gallon waste tank with washout port and 30-gallon freshwater aluminum tank.

“Moving a portable restroom for a rental company is time-consuming and certainly not cost-effective for people who are on the go all the time, like tree trimming and roofing companies,” says Jay Poust, inventor of the Tow-Let portable restroom trailer. “They’re on a roof one day and the next day they’re on a different roof. They need a portable restroom, but they’re not going to pay a company $150 or whatever to have it there for a day. I thought if they had a unit that they could pull behind a truck, wouldn’t that be a great idea?”

Each flush uses about 2 pints of water (about 100 flushes per fill). The lockable rear-mounted storage box includes pump, charging system, hose and room for supplies. The waste tank has a sloping bottom with side-mounted dump valve.

“The biggest advantage to the consumer is they don’t have to look at human waste,” Poust says. “It’s just like a toilet in their house. It’s a functional restroom.”

The trailer is 150 inches long, 90 inches wide, 104.6 inches to the top of the restroom and about 9 inches above the ground. Trailers have a 2-inch ball hitch for towing and feature rear stabilizers, steps, handrails and a front jack.

Other models include the Twin with two flushing units on one trailer for larger work crews and special events (260 gallons waste, 210 gallons freshwater) and a Standard non-flushing restroom. The Low-Ryder trailer, available with or without restroom, can be built to specific needs and customized in company colors. The trailer can accommodate any brand of restroom.

“Mobility is what makes this product the innovation that it is,” says owner Ivan Craig. “You can pick them up and go from site to site quickly and easily without having to worry about a mess. You just pull up to an RV dumpsite and empty the refuse tank.” 712/623-4007; www.tow-let.com.
