Thanks all for the discussion.

I just got mine delivered on thursday the 14th. It's a very nice unit. Can't wait till spring to start using it.

I apologize if I’m posting this inquiry incorrectly... I’m still a fledgling in trying to negotiate questions in this forum with an iPhone.
My inquiry is that I have a 195... the weight of our tote tank is about 40lbs... it’s designed for transport on the rear ladder... has anyone had any weight difficulties in securing it the back ladder while bouncing down the road?... Thanks

Yes, I jacked up each side with a floor jack, then slowly lowered it down onto the Sherline.  The bad thing is that it's a little hard to see under there.

I've used the Sherline to weight the whole trailer, first tongue, then at each wheel.  It was pretty close to what I got at the CAT scale.  I wouldn't trust it if you're right at the limit of the trailer's gross weight capacity, but if you are under, it's plenty accurate.

I guess if you are right at your tow vehicle tongue weight limit then you might need to weigh the tongue every time, but I’ve only weighed mine once or twice. Once you have your loading settled you will know the range the trailer and tongue weights will be in and you shouldn’t have to weigh again unless you make a major change. By far the biggest variable is whether and how much water you have in your tanks, water is heavy, a full 30 gallon rpod water tank weighs 250 lbs.

If you do make a major change and don’t want to re-weigh you can easily calculate the change to tongue weight from adding or subtracting a load. Think of the trailer as a teeter totter rotating around it’s axle. This is the same method pilots use when calculating weight and balance in airplanes so it’s safe and accurate.

Change in tongue weight = (distance from weight to trailer axle x change in weight)/distance from tongue to axle). Add to tongue weight for loads added in front of the axle and subtract from tongue weight when removing loads in front of the axle. Do the reverse for loads behind the axle (subtract from tongue weight when adding and add to tongue weight when removing).

I ordered the one I had mentioned earlier (and below) from E Trailer. I wanted to make sure there was no sudden rush in the spring. Using the scales at a truck stop might work, especially if you want to know total weights. But for tongue weight, you have to go everytime you load, unless you keep everything the exact same, which seems unlikely. I think if you can put the scale under it as you load up, it's a much easier way to do it. The sherline looks good, but I trust E-Trailer more than Amazon.

I have the Sherline; Amazon.com: Sherline LM 2000 - Trailer Tongue Weight Scale 2000lb: Home Improvement 
The CAT scale is great to make sure you are in specs.  The Sherline helps when I am balancing for tongue weight because I have to be at 350 lbs because of my hitch rating.  I can't recommend the BetterWeigh just not accurate enough.

Why not just go through a scale twice? Once with the trailer, once without. Remove tension on the wdh if you have one. On the first weighing, get the tow vehicle weight, then the whole rig. On the second weighing, get the tow vehicle by itself. You’re using a calibrated scale that you can trust is accurate. Might even get it done for free at your county waste transfer station.

Tongue weight = tv with trailer - tv without.
Trailer weight = total eight with trailer - tv without.

You need that total rig weight anyway to confirm your GCVWR is within specs.
