I got my water tank setup complete over the past week as well. After going and looking at them, I ended up with a smaller 35 gallon portable tank. The 50 would have taken up more truck bed room than I was willing to give up.
Here is the 35:
Added some hardware for the ability to have a shutoff and attach garden hose:
Buddy gave me this pump so that water can be pumped from the tank into the camper if needed:
When the tank is full, I can move it around the bed of my truck without issue. I position my truck with the rear facing the campsite and it comes in really handy for filling up squirt guns, rinsing cast iron skillets and cooking utensils, etc. We stayed 5 nights over this past weekend and I ended up adding 15-20 gallon to our fresh tank to get us comfortably through the last day.
