We picked up our new E19 on 9/12/2023 and this is our first trailer. On the way home from Chilliwack I went the Cat Scale in Ferndale. The trailer was basically empty and the dry weight was 3500 pounds. I bought a Sherline tongue weight scale. The trailer is empty with full propane tanks and I used blocks to get the trailer level on the scale.
The scale weight read 500 pounds. My wife got on the bed and the weight was 450 pounds. My 4Runner has a maximum hitch weight of 500 pounds.
These values seem high and are not close to the ETI specs for dry hitch weight, 305 pounds.
Our driveway is slightly sloped, 3" in 15 feet or about a 1% slope. Will the slope of my driveway give me an inaccurate hitch weight?
It seems slightly high to me for a completely empty trailer, but not unreasonable if loaded for travel. I would attempt to remeasure on level ground.
My E19 has a dry weight of about 3650lbs and an over-the-road weight of 4000-4200lbs. I recently measured the hitch weight at 460lbs. That included full propane tanks, about 50lbs+ of stuff in the front storage box, lead acid batteries plus another 30lbs of tools stored under the dinette seats, a full fresh water tank, and empty grey/black tanks.
your slope is closer to 1.7% and if the trailer is level then the rear axle's suspension is compressed more than the front axle if the slope is sloping down toward the front of the trailer. That will place more weight on the rear axle and move the balance point to the rear. This will increase the tongue weight significantly. If the slope is sloping toward the rear and the trailer is level then the tongue weight will be less because the balance point or fulcrum will move forward.
