We got an anguished question from a reader: “My husband insists there is nothing wrong with leaving the truck hooked up to our fifth-wheel for extended periods of time. And when I say extended, I mean two weeks. … If there are reasons why you should not, what are they? … Perhaps if I knew any reasons why this should not be done, I could convince him it’s not such a good idea. He has a hard head, but I think he will listen to your reasons, if applicable.”
Hard-headed husbands are our specialty – after all, one of the two of us fits that description. But that’s a story for another day.
So, is it “not a good idea” to leave your fiver hitched up to your tow rig for extended periods of time? We went to the horse’s mouth for a technical chat on the matter, taking up the question with the folks who make PullRite hitches.
Admittedly, the question must have been a bit unusual, as there were a few moments of silence at the other end of the line when we posed it. PullRite’s tech guy couldn’t find anything “bad” happening if a fifth-wheel hitch is left holding onto the fiver’s kingpin. He recommended that routine maintenance on the hitch system be performed, as standard procedure. But from a technical standpoint, you won’t harm your hitch, your kingpin, truck or trailer, if you decide you don’t want to uncouple – even for long periods of time.
From a convenience perspective, staying hitched up could go either way. If you pull into a site and plan on staying a night or two, unhitching can be downright time-consuming. Assuming you park in such a way that your fifth-wheel’s nose isn’t “down in front,” you should be able to do a fore-and-aft level without much difficulty, simply by raising the rig up as needed using the rig’s landing gear. That will take a minute, but if you unhitch, you’ll still need to do that leveling after the rest of the work of getting off the truck is accomplished.
To the plus side, staying hitched up can also give you a more stable experience, as the truck will act as a solid influence under the kingpin. We seasonally camped with a couple for a number of years. Whenever they unhitched, he had to immediately set a tripod stand under the kingpin, because she could only imagine the whole rig would pitch nose downward the minute someone climbed up in the front. Of course, this was imagination, and she knew that, but something about having an unsupported front end just gave her the heebie-jeebies.
But don’t neglect the drawbacks: If you intend to stay put for very long, if you need the truck for running errands or sightseeing, our experience is that dragging any sort of fifth-wheel around town is a definite … well … drag. Parallel parking a fifth-wheel and tow vehicle just isn’t our idea of a lot of fun.
But a side-note to the “new” or “contemplating” fifth-wheeler: If you decide to drop off the fiver and use the truck for tooling around, don’t make the common rookie mistake! Don’t jump in the cab after unhitching, step on the gas, then feel the awful, gut-wrenching THUNK that comes when the kingpin hits your tailgate because you forgot to open it first. Same goes for the TWANG of electrical connecting wire that severs itself because of that mental infarct that caused you to leave it plugged into the truck receptacle.
Keeping all the other details in mind, it’s perfectly OK to leave that combination tied together – overnight or for weeks on end.
