Trailer question with adaptive M suspension

[bjcarls]

I will be towing an enclosed featherlite trailer, about 400lbs of tongue weight and am wondering how much does the air suspension compensate for the trailer weight?
The real question, do I need to add additional ball height to compensate? My old X5 would sag a good 2inches, without air suspension though.

The air suspension by design will work to maintain proper ride height automatically. I did not notice any sag when towing with my X5. In short you shouldn't have to raise the ball 2' to compensate.

Agreed. You should no issues towing. I towed a 14' open with a race car. you have to constantly have to remember that there is something back there.

400lbs of tongue weight is a lot. I've had 300lbs with m adaptive and can say there was no sag. By design I think you should be fine.

It's probably closer to 300, trailer alone is 200 but I back the car in over the tandem axle to even it out. But I load the rear area with luggage and kids so rare weight is probably maxed out.
I ordered invisi hitch so I'll post pictures of all of it when complete.
