So the vehicle itself was empty, it only contained 6 passengers (2 in carseats, 2 teenagers, and 2 adults). The squat is not nearly as bad as it looks in that picture, it's hard to see but the vehicle is actually at a slight lean on the passenger side plus the darkness really doesn't catch the wheel's well.
Trailer had less than 10 gallons of fresh water, enough for some road side stops. We had 1/3 tank black, and empty grey leaving (in the picture with the wheels circled), and on the way back we had 2/3 black and 1/3 grey which also took some tongue weight off.
Trailer has nothing stored in the front pass-thru, with the exception of the setup stuff like hoses and misc small tools. It did have 2 full propane tanks, along with 2 batteries. All other storage was put under the bunks in the rear of the trailer, which I would say comes out to around 500 pounds I put in that area. (firewood, tables, chairs, etc.) We also have an outside kitchen area which has storage where all the drinks were stored, and that is a lot of weight for sure.
Rear suspension is not fully compressed, regardless if some people believe 500 lb will compress the rear end. With the trailer on, and all the kids in the car I can stand on the tongue and still get another 1-2" of compression easily.
If you ever drove CA freeways, you know that they are bumpy as can be and will throw you all over the place. I have towed with many vehicles before and to be honest I never felt I was not in control and I never lost any steering, even hitting some insane size bay area bumps. I am not joking when I say these highways have bumps that literally make cars bottom out on the highway constantly.
Now for the downside..
I have full out snow tires on this car right now, and it was never my intent to ever leave town with the car with these tires but a blow out on the stock's caused me to get screwed over. These tires were not made to handle the weight this rear end had on it, especially with the soft rubber.
What I intend on doing is finding maybe 5 rims, and mounting some towing tires on them for the car. I say 5 because incase of a blow out I want to be ready. This spare will be mounted next to the trailer spare on the rear bumper.
Second thing I am thinking either A. Stiffer rear shocks (I can care less how the car feels unloaded), or B. Drop some air shocks in the back to get it more sitting level. Trailer is sitting level, no tongue down.
500 lb tongue weight is crazy low when talking travel trailers, and I know I am over that 500. I did not hit a scale as for some reason each scale I passed on I5 had lines of people waiting, but I will be hitting a scale soon. The dealership was happy to hook it up, try to sell me on a WDH and then send me on my way. Also when I did my test drive, they had the fresh tank completely full and I still had full steering and rear was not fully loaded.
Would I tow this across the country on this setup? Nope.. There are better setups for that.
Would I tow it 1000 miles away? Yes I would.
Now the question for Robert.. Who makes air suspension for the rear of this thing?
