I agree the transmission temp is the limiting factor but 100 degrees? Oh, you must mean 100C = 212F. That makes more sense. And 115C = 240F.The transmission temperature will likely be a few degrees warmer but should not exceed about 100 degrees. Pulling on a level road is the ideal, it is the starting from a start that really heats up a transmission, through the torque converter. If the fluid gets beyond 115 degrees, get the fluid changed when you return home.
Bent is being as kind as possible with virtually no info to go on.Thank you bent nail for your thoughtful answer. I am as green as they come. Are you sure your not a mind reader? Kindness goes a long way in this world.
... I am adding a weight distribution hitch with a sway bar. ...
For best sway stability I'd prefer to have closer to 15% weight on the hitch and the weight transfer bars will lift the hitch effectively taking weight off and transferring it to the front axles.dry hitch weight 332lbs... that is really close to the 350lbs hitch rating, add a battery and propane tank and you will be over 400lbs, load the back of it, and try to limit the hitch weight to under 350, and to about 12% of total trailer weight
15% might be good for a truck with a real frame and a 1/2 ton payload, but with a unibody like the rav4, I would not want to overload the 4 bolts attached to sheet metal unibody too much. the WD hitch will remove weight from the rear axle, but it will not remove weight from the frame bolts...For best sway stability I'd prefer to have closer to 15% weight on the hitch and the weight transfer bars will lift the hitch effectively taking weight off and transferring it to the front axles.
I don't trust a sway bar to do anything for me and thus never use one. IMO, it's a "crutch" that's not needed once trailer weight is properly distributed.
