The tilt you are suggesting I would assume is more tilt. Correct? I'll give it a try.

Yes, more tilt.

Not exactly. 860 is your increase in rear axle weight at loaded tongue weight. If you weighed the trailer unhitched with the axles on one pad and the jack on another, you'd get actual tongue weight. It's probably close to 860# but not exactly, I would expect it to be less than 860# because you have a "lighter" front end. That missing weight is on the rear axle.

I keep a Sureline scale at home. Pretty handy for all kinds of stuff, but mostly the trailer. Sherline Trailer Tongue Weight Scales

A Sherline scale is on my list of tools I would like to have. Where is the best place to buy one?

I can't remember where I got mine. That site lists McMaster Carr as a distributor. I'd hit the web and see who has the best price. I got the 2000# one since my trailer is potentially heavier. Not sure if you want a 1000# or a 2000#. I'd opt for 2000#, I think.

I think the tongue is gonna be 860, the truck was (3680+3420)=7100 and the truck with the tongue weight was (3340+4220)=7960 with no WD. Dat's alot of tongue!

ooops, you're right. I was thinking the second set of numbers was with WD. didn't read it correctly. That IS a lot of tongue for a 25'er. You may want to move some weight back in the trailer and leave the head tilt alone.

I'd move about 150# off the tongue weight. Remember moving 75# from front wall to the back wall will remove 150# from the tongue weight. (not exactly, but you get the picture)

Total trailer weight = 6040

Presently 14.2 % of total on tongue

at 710# tongue weight, you'd be at 11.75%

I agree with the above suggestions that your rig could be made more safe with some simple changes. My naive reasoning is as follows:

1. We know that trailer instability is often caused by the truck steering wheels being lifted so that the correcting ability of the steering is reduced.

2. When we are towing we would want more steering force available, not less, for obvious reasons.

3. Therefore we need load distribution systems to achieve this. In your case the down force on the steering axle is reduced by 80 pounds from solo running, so you have less steering ability when the trailer is attached, the opposite of that which we desire.

If this was my rig I would adjust the hitch and tongue weight to at least get rid of that 80 pounds lift.

I should not have any problem shifting 75 or more lbs to the rear. I am storing some heavy stuff under the sofa and in the forward overhead.

I need to go ahead and order a Sherline scale.

I have to do the same thing next spring. Got a new Arvika bike rack for the tongue. So 2 bikes, the rack, and motor scooter ramps will now be on the front of the trailer. That's about 150# of increased tongue weight. (Well not really, cause the bikes used to ride in the living Room...but they're moving forward about 6') Anyway, AS is going on a diet and move some weight around first thing come March.

You'll find that the Shurline will be used at least once a season just to check things out, and each time you do something significant to your load.

The Sherline scale scale is an example of function through simple design. It utilized a piston with a surface area of 1 sq inch. The mechanical gauge is most accurate mid scale, but reasonably accurate across the dial. To change the range of the scale, you only need to swap out the pressure gauge as they read directly in PSI.

This site has some useful info:

I seem to remember that....must be why I got the 2000# unit. I see they are now graduated in Kg's as well for our metric friends.
