Do you pull you PUP with a full or empty water tank and why?

    Just curious it seems like there might be undue stress on the tank when pulling with a full tank or should I not be concerned.

    Empty! Fill up when you get to the CG, or slightly before you get there, it reduces weight on the tongue and it keeps you from losing control of the sloshing water inside.

    Doesn't make sense that a manufacturer would install a system that couldn't be used, but I've been wrong before. [RTM]. My guess is the tank is engineered to be filled with water and used for it's intended purpose - transporting water to the campsite, HOWEVER, I have noted postings on this and other forums that there are some designs that place the tank far behind the axle making for a possible light tongue weight and sway situation if the balance is not restored by shifting other weight forward. That part of the design would be my only concern.

    My Jayco does not have this issue and we fill it at home and typically transport the water on 2-3 hour weekend trips boondocking in the National Forests where there is no water. If traveling further, like an 8 hour trip to another state, we will tend to find a place to fill it closer to our destination

    Some won't travel with it full simply to save weight and achieve a somewhat better MPG towing.

    My fresh water tank is 30 gallons, at roughly 8 lbs per gallon that's only 250lbs out of my total capacity of 7600 (I have a small TT). It's really not worth monkeying with but for some reason I like to carry it empty. Although it takes a few minutes to fill it back up at a fill spot. (More than I thought it would). Our next trip is local and I'm going to try driving loaded up. I doubt I'll notice it, my tank sits before the axles.

    Honestly depends on where I am going. If I know the cg has good water I will run with whatever I have leftover from the last trip. If they don't have good water I will fill most of the way at home and top it off at the park.

    I prefer the known quality of the water that I can provide at home. My trailer tows perfectly with a full tank of water so there is no sloshing. And, it's one less thing to have to mess with when setting up as we normally do not have water at our site. No problem for the past seven years and if it becomes one I'll reconsider.

    I have never had any issues with loss of control due to water sloshing. In fact, if the tank is filled, I don't see how there could be any sloshing. But again, my Jayco has the tank (19 gal) positioned pretty much right over the axle. Never ever an issue with swaying.

    I have towed it empty and full. Absolutely no difference. It may depend on your TV, but my F150 couldn't care less. No difference in handling, mpg, etc.

    If going dry, then fill it. If connecting, then don't. It's up to you.

    When we are camping with hookups, it's empty. Campground with no hookups, we fill up the tank there or somewhere nearby. We don't use this water to drink but for other necessities. We bring our own drinking water in jugs and bottles. Boondocking, we fill up at home. There's no noticeable difference in towing empty or full.

    We bring a full tank, we like the lack of smell and taste of our water

    I have found that my Westlake tows better with the tank full. I think it helps to offset all the junk I load in the front storage box. [:D]

    There is no problem towing with the tank full or empty. Personal preference.

    Full. No way to fill at the CG, other than toting 5-gal aquatainers back and forth from a central spigot. No thanks.

    We tow the HTT empty. The weight is the main thing. All the camp grounds we stay at have potable water hook-ups or fill stations.

    I agree. I don't even have a battery so I wouldn't have any way to get it out of the tank. To my knowledge, it's never been filled.

    I tow empty if I know there is water where I'm going. But, I often boondock (camp in wilderness outside established campgrounds) and when I do that I tow with it full. When I'm on a long trip with multiple stops I run it down but leave about 8-10 gallons, which I tow to the next location, then refill it there. I like to tow with little or no water to cut the weight.

    When I fill at a CG that's the way I do it. Most of the places I go have no other water source. I don't do it all (40 gallons) at once, though. A couple of trips now and then throughout the day and I'm good.
