No issues. Everything pulls fine fully loaded on my load test runs. When we had it out on the road, I would typically only have 15-20 gallons in it. I wanted the bigger tank "just in case". There are 3 of us and needs change from trip to trip.30 gallons is 250 pounds. That is a lot of weight, have you seen any problems since install. I was thinking 20 gallons max.
I'm am running a 21 gallon tank and 12v on demand pump that runs off my deep cycle set up. Installed over the axle on the right side of trailer. Cargo and gear on the left side balance it out nice.Am starting to design an off road trailer. Am considering installing a water tank and need some ideas. What did you use and where did you end up installing it?
