FWIW, I have a 26' 5er with rear kitchen and aft FW tank. I've done the math and 500# of water lowers the pin weight 100# and adds 600# to the axle weight. Your result may vary somewhat depending on length of trailer, size of tank and location of tank.
I usually travel with the tank full, because we mostly dry camp. Handles just fine.
We have a slightly shorter 5er and had about the same results. 40 gal tank at rear added about 500 to trailer, took nothing off the hitch(weights taken at different times, so math doesn't work out perfectly). I can't tell any difference in handling. We also have a second 80 gal tank in the rear, but I have never driven on the road with it full; only fill when entering a campground.
