I'm still nose up with the hitch shank flipped up and the shorter ball. I measured at different places in the parking lot and got between 5/8 and 1 5/8 from front to rear. These ranges were obtained by measuring at a few different locations in the parking lot. If I had to pick one location that seemed most optimal the reading was 1 3/16 nose up.
I also tried to use a 2 foot level on the ground and found that a quarter and nickle were needed (on the front/car side of the level) to make it level and on the frame directly above the the same quarter and nickle were required.
I'd like to better understand the purpose of perfectly level to nose down on the trailer. Is it all about tongue weight?
The trailer yellow sticker weight is 7386(GVWR 9858). There's not much stuff in there yet, so if the yellow sticker can be trusted then we're still very close to that weight.
According to a Sherline scale my tongue weight is 925 (averaged 4 readings) with 49 gallons of fresh water. This is is my as tested weight. I drained the water and got an average tongue weight of 875 lbs. This small difference makes sense because the water drain is just in front of the axles.
That puts me at 925/(7386+400) = 11.9% for tongue weight.
Also these measurements are over a distance of at least 25 feet. So, we have sin-1 (1.1875"/300") = .0006 degrees. If my math is right and we consider degrees vs inches then it seems pretty level.
I'm still new at this so will defer to you experts whose help I greatly appreciate...
