Towing with Full Water Tank?

Okay I realize that towing with a full tank of water adds a lot of weight. My Cougar has a 60 gallon fresh water tank. I have it at home and am planning on camping Memorial Day Weekend at a State Park. They have water but it will be busy so I thought why not fill up at home and then I could ho directly to the campsite.

Can you guys give me rationale why I shouldn't haul water to the park two hours away? Pros and Cons please! Thanks in advance for your opinions...

  • I have a 92 gallon fresh water tank and if I'm dry camping it is always full when I go. The manufacturer designed your trailer to be towed with fresh water in tank.
  • For 30 years have travelled with full water tank when we will be staying where unable to get water...2 TTs and one 5th wheel no problems.

    I did see an idiot weaving through traffic at 70 +MPH towing a 25 foot TT. A few miles down the road he was pulled over to the side with his full water tank laying on the pavement. It had broken loose, smashed through the side of the TT and ended up on the ground.
  • We frequently tow with full water going and full waste coming unless we are expecting full hookups.
  • My fresh water tank is only 40 gal, but we always fill it full before we leave. Never have had an issue.
  • This has been discussed before. A 60 gallon tank will weigh 480 lbs. What percentage is that as compared with the total weight of the RV? If the RV weighs 15000 lbs it is 3%; 10000 lbs it is 5%.
    I rest my case.
  • I also have a 60 gal fresh. Mine is over the axles, but still extra weight. In your situation, I would fill mine at home, to save the hassle, when you get to the CG on a holiday.

    If I go a longer distance, I usually fill when I get there, if I know they have good water. The camper is made to travel with the tank full, so no reason you can't fill at home, if you can handle the weight.

  • Nope. I do it all of the time. Much more convenient, it's nice to be able to stop on the road for lunch or a potty break as well. I have a Flo-Jet macerator/pump so I often skip the dump lines and dump at home as well.
  • I have no rationale why NOT to.
    That's what the tank is for..........holding water and traveling.

    We FT'd for 7 yrs. I always traveled with at least 20 gallons but got caught short one time due to lack of water (main line broke) so it was a full tank from then on.

    When towing....weight plays a factor to a certain point.
    Wind Drag is the bigger mileage killer.

    Besides......once you hook up mileage drops to what it is.

    I like having water...especially when I know where it comes from/taste/quality.

    Fill it UP. You're only going 2 hours away :S
  • I would think that your tank hanger straps would be unduly strained carrying all that weight and all the bumps you go over. JMHO
