Review of Portable Toilet in a Big Truck:
The type we bought in the early 1990s was a Thetford Porta Potti® 135.
We considered this item to be even more important than having a bathroom at home because it served not only as a toilet, but also as a collection point for all waste water from
The Thetford Brand
Although there are different brands and designs for portable toilets, the only experience we have had as commercial truck drivers is with the Thetford brand.
Thetford sells a number of different size portable toilets, all of which have two basic parts which we call a water reservoir (upper) tank and a waste holding (lower) tank.
Attached to the top of the water reservoir tank is a seat and lid. There is also a bellows that upon being hand-depressed, pumps water from the upper tank into the bowl to "flush" waste toward the lower tank. A handle on the front of the waste holding tank slides open or closed the "door" through which the waste and flush water flows. When pushed in, the door to the waste holding tank is closed.
Assembling and disassembling the Porta Potti® is very easy. The two tanks fit together and a slide mechanism locks them together. (In a newer model, the lock is automatic.)
To dump the contents of the waste holding tank, disassemble the two parts, carry the lower tank to any regular commode (such as at a rest area or truckstop), swing out the capped pipe, remove the cap, hold the pipe over the toilet, tip it down toward the bowl and press the air relief valve. You may wish to start flushing the receiving commode just before dumping your portable toilet so that the waste is removed quickly.
When the waste is evacuated properly, your hands never touch it. (You can't say that about putting waste in a plastic bag or bottle.)
In general, the higher Thetford's model number, the larger the tank capacities or accessories. We upgraded from the 135 model to the 155 model because of the increased capacity of the waste holding tank (which means fewer trips to dump the waste). As we recall, there may also have been a problem with the bellows leaking water. We have never once had a problem with a leaking waste holding tank.
Mike now has over 11.5 years of professional driving experience. In all those years, the only time when he did not have a portable toilet in his truck was the 13 month stretch that he drove for Schneider, a trucking company which forbade all such devices from their trucks.
Supposedly, the company's leadership was afraid that they would leak and damage their trucks. Whether this was just a suspicion or they had had a problem with a leaking mobile commode, we do not know. We feel strongly that if they were to investigate, they would find that the Thetford brand is advertised as "sanitary, odorless, and leak proof."(1)
Cleaning the Porta Potti® is probably easier than cleaning your home's commode. When we still had a residence, Mike would scrub his device's exterior with dish washing liquid and a rag under running water outside, and let it air dry before putting it back in his truck. Now he uses a different cleaner but still rinses it under running water.
The great advantage of having a portable toilet in your truck is that you no longer have to depend on the availability or cleanliness of restrooms on the road. You don't have to wait for the shipper or consignee to open up to use their facilities. As for restrooms in some rest areas on the road, some are not cleaned as often as they should be. You don't know who last sat on that public toilet or what he or she left behind for the next sitter to pick up! In some cases, rest area restrooms are not open to the public 24 hours every day.
Any time you're parked, you can use your portable toilet. This convenience has come in very handy over the years. Vicki recalls a time years ago when she was driving east across Nebraska late at night. She had eaten something for dinner that didn't agree with her and it roared through her like a freight train. With no rest area anywhere nearby, all she had to do was park temporarily on the shoulder of an off ramp, go back into the sleeper, use the portable toilet and be on her way again. She didn't even wake Mike, who was sound asleep.
|As important as we feel it is
to have a mobile commode in one's truck, it is just as important --
even absolutely essential -- to use a holding tank deodorant to break
down and control the smell of the waste.
|There are different brands of
deodorizer available. We have only ever bought the dry (powder) "Campa
Chem." (New units we have bought come packed with the liquid variety.)
Mike reports that the formaldehyde-free powder does not
work as well for him as the regular powder does.
Mobile commodes can be used in other places besides a truck. Some people take theirs in boats. Most RVs come with built-in bathrooms, but they can be used in recreational vehicles without one. We took our portable toilet with us on a camping trip once and it performed admirably. (No more using nasty camp site toilets!)
The Porta Potti® is solidly built, unlike some emergency toilets that consist only of a seat on a frame with a bag suspended underneath, like the one shown at left.
Personal and Truck Security Issues
While there are tangible benefits to having a portable toilet in one's truck (that we share below), there are some intangible benefits, too:
The only potential drawbacks we know of to using a portable toilet are trying to overfill either the water reservoir tank or waste holding tank.
We strongly recommend the Thetford Porta Potti® portable toilet for use in an 18-wheel commercial motor vehicle. And, of course, we recommend that users clean their hands after use of any toilet.
Update: We wrote about reasons why you should consider having one in your truck.
