I agree with dlhoppe.
NomadMan, If your WDH is adjusted properly, then there should not be a noticeable sag in the rear of your Tundra. Yes, it will still go down some when you hook up your trailer with the WDH.
You say you have already adjusted 1 notch. Me thinks you need to start from square 1, and do the fender measurements as outlined in your instruction book. It sounds like you don't have enough weight distributed to the front axle, but you don't want to put too much weight up there either....hence, then fender measurements to tweak your system.
I don't see the 18SS listed on the Stealth website. If you are referring to the SS1812, then it lists the tongue weight at 608 lbs. That is pretty heavy tongue weight for a listed 4240 dry weight trailer, but bumper pull toyhaulers tend to have heavier tongue weights so that when you load up the back, then you will still have enough tongue weight. It would be good if you could get an actual tongue weight after you get your toy(s) loaded and the camper ready for the road. That way, you can make sure you have the properly sized spring bars. Undersized spring bars may not give you the weight distributing that you need, and oversized spring bars might give you a rough ride and add extra stress to the Tundra hitch.
I am a believer that a properly sized and setup WDH will work with most
trucks and trailers. I am also a believer that air bags should seldom be used on 1/2 ton trucks, especially to correct a weight distributing problem......as dlhoppe stated, air bags will not get the weight back on the front axle. A 1/2 ton truck has a semi-floating rear axle that can easily be overloaded, causing premature axle failure. Air bags will not increase the rear axle rating, and will not increase the listed towing rate for a vehicle.
