I raised my trailer 3", upside is lots less dragging donkey, downside is nothing IMO.

Gas mileage for me is unchanged, as is handling. The change in the center of gravity made no difference for me whatsoever.

It should be noted that even raised, the center of gravity of my trailer is still lower than most every SOB.

Did you use the Dexter lift kit?

How to gain more clearance

No, I made my own setup that allowed me to strengthen the frame fore and aft of the axle attachment.

My old trailer needed to be straightened and reinforced in this area so I added a 3"x3" by about 8' angle on each side.

In essence it is similar to the kit except it is welded in and much longer.

I welded these in while I had the trailer jacked up very near the rear of the trailer thereby removing forty years of sag.

It still shortens the time/distance involved in trailer sway initiation. That you do not find it objectionable is another thing. I would have made the same choice, but three inches is a change that doesn't sound like much yet is.

TT weight on axles, TW, choice of trailer tires & their pressure plus your hitch all help offset potential problems with this modification. Belt and suspenders.

As to mpg it is with crosswinds that now have more access to the TT underside that it would show. There will be more lateral stresses on TT tires. No way around that.

I would agree that in practice your summation that the differences are hard to perceive would be my hoped for outcome.

I have seen vintage kin trailers that rolled and were destroyed. TV rolled. Raising the TT body, on leaf springs, with bias tires, with a friction bar hitch and pulled by a slightly raised heavy Suburban was enough on the day trouble came. I think of it as tolerance stack.

Sort of like tire pressures opposite of recommendation. Too low on TT and too high on TV. I've seen that around here.

Then, years down the line on the wrong road on the wrong day . . . .

I've seen 5'ers that sat so high I wondered if any little bump would upset them. That's one of the reasons why we're not considering 5'ers.

It made no difference regarding an inclination to sway whatsoever, even after it was raised and before the Hensley.

The surface area that would play any part in crosswinds was essentially unchanged, it was simply the same surface area 3" higher.

The best way to avoid accidents is to not drive a vehicle beyond its safe limits, no matter what these limitations are.

The area under the trailer. Volume. It allows more interaction with the difficulties found in the air between TV and TT. As well, the most difficult area of all, and that is at the tail.

Note I did not say at any point it has become a danger. Lowering it would not be a noticeable difference either. Except that the trailer would be that much more resistant to any forces acting on it.

The factory setting is not a random choice. There are models which can be used for prediction.

When we lean hard on those we start to get outside of predictable behavior. Same as with tire pressure. We narrow the envelope. It is not a free lunch, nor fair to say that it is.

There is a tendency among many to over analyze things that amount to nothing.

Frankly, for me the fact that every bump or street entrance and egress is not a potential challenge adds a ton to overall safety.

When I rebuilt my trailer, I discarded a lot of factory build stuff.

I haven't found that those are a challenge, much less that they are unsafe. The longer the trailer, the fewer the places one may go. If that constitutes over-analysis it is because of understanding boundaries. It is not a shot in the dark.

Frankly I don't much like dragging donkey getting in and out of half of the gas stations across this great nation.

I suppose there are places that my 31 footer should not go, but Gas stations shouldn't be one of those places.

It is real simple from where I sit. My trailer was too low for my tastes so I raised it up.

I have stated that this caused me no negative consequences, I said this because I believe it to be true.

If you choose not to believe me then I guess I will have to get used to being a liar in your eyes. I can live with that.

It isn't black and white, is the point. It is making one trade off in favor of another.

How to gain more clearance

For me there was no down side.

What If a person wants to leave their trailer stock height?

I think that is great!

What if a person wants to raise their trailer up?

I think that is great too!

Is it possible that raising a trailer three inches might adversely affect trailer handling? While it is not my experience at all, I suppose lots of things are possible.

I have posted on lots of forums, I have never posted on a forum with so many people who want to make any statement that disagrees with their personal opinion controversial.

If I and others think that our stock trailers are too low, why do you disparage the action of raising them up when you have never even pulled my trailer that you call ill handling?

Except that your trailer is now somewhat less able to keep itself upright.

And if you really read what I wrote you'd have seen I agreed with your solution to a saggy frame.

Which is still not the same as saying it is a free lunch. It was a trade. And the only thing one can say in reducing road ability is "so far, so good".
