Dolley Trailer or Four Down?

Four down won't make much of a difference. The dolly probably weighs about 500-600 lbs. Once you add a base plate and tow bar it adds a couple hundred maybe. Get a lighter toad. The smallest weigh about 2300 lbs, the next step up is about 2800 lbs. I went with a Kia Soul(2800), a bit more weight but much more room.

Well, you're vary vague post of "struggled" doesn't help much.
Don't expect a big gas class A to be a towing monster. That drove train is already about 90% used up just hauling the RV.
No, 4 down won't make much difference IMO.
Again, depends on your definition of struggling and your basis for comparison.

Agreed, subcamper, but 9000 pounds was OP’s number.

Might want to post this on the Motorhome forum.

We tow a Honda Fit, weighing in at around 2500 lbs. Four-down towable if equipped with manual transmission.

When you go looking, always go by what is written in the owner's manual, not by what you hear.

There's no way a Grand Caravan (even with a dolly) has a GW of 9000lbs.

Empty Grand Caravans weigh about 4400lbs. With a 2-wheel dolly and a few things in the van maybe 5000lbs.

A lighter vehicle might weigh 3000lbs instead of 4400lbs for the Grand Caravan, so you wouldn't save much there. Dropping the dolly would only save a few hundred pounds.

Way too much load. You need a smaller, lighter towed.

You’ve been lucky. Stop now.

I don't thing doing away with the weight of the dolly is going to help you that much. You are trying to tow more than the coach is rated for.

The Gross Vehicle Weight Rating for the Sightseer is 22,000 lbs. The Gross Combined Weight Rating is 26,000 lbs. A fully loaded coach plus the Grand Caravan puts you 5000 lbs over the GCWR. That is your problem.

Another issue is the trailer hitch for the Sightseer is rated at 5000 lbs.
