When we load our 06 lc for vaca and have 5 or 6 people, it goes to low. Pops back up when some of the weight comes off.
 
I mean it's driving fine and I don't think I've felt any bottoming out @melt6366
 
I just crossed into Oklahoma on 40, when people get out out it goes back to N
 
4 guys 2 girls and our luggage in here from Georgia to CO
 
Probably a combo of weight and worn rear springs. New springs and a spring spacer from slee would drop your pressures back down and the ahc would be better at handling the added weight.
 
I still have 730 miles to where I'm going, should I be ok if I'm easy on it, cruising at 66mph

Hmm so trying a fluid change wouldn't be a good move
 
Because I found a Lexus dealership in OKC that is on my way

Not a bad idea to do a AHC fluid swap when you get home, but to lower your neutral pressures will probably require torsion bar adjustments and new coil springs and/or spacers in the rear to prevent it from dropping to low. If all of your driving is on highway you should be fine.
 
Well it's 600 to where I'm going and then 1550 home at the end of the week
 
as long as it feels normal, I would drive as if it was normal. or pick up a liter of fluid at the lexus dealership and add it.
 
Just don't carry a 20 ton jack in the back like @aaronrules and you'll be fine.
 
Same thing happened to me on the way to HIH7. It's a result of too much weight. It may not be possible on this trip, but the quickest fix is heavy duty springs. If you can find a place that has them, snag them up and get them installed.
 
Funny, this just happened to me on our road trip last week. Too much weight I guess. But I've had the Cruiser since new and hauled boats and stuffed it full of gear and people, but never had it give up before. I'm guessing the springs are tired at this point, like taco47001 suggested. It didn't really affect handling and after we drained our six gallon water jug it was okay. Must have been right on the limit! Looks like it's time to call Slee...
 
For every 1MPa that your static rear neutral pressure is too high you're sacrificing about 210lbs of cargo/passenger weight over the rear axle. Even worse, by 25%, for weight over the rear bumper.
 
Can you confirm that the vehicle has physically gone into low, or is it just the indicator light on the dash that is on? When the suspension is overloaded, the light will switch to low to indicate that the pressures are too high, but it won't actually change height and is still fine to drive. Easiest thing to do is grab a 30mm socket and a breaker bar and crank the torsion bar bolts clockwise a few times each (4 turns equals about 1 mpa of pressure decrease on the hydraulic system).
