We haven't been at it long either and started off towing with a dolly. I towed my 2003 Dodge Grand Caravan and never knew it was back there. My only problem, and I have never figured out why, when I unloaded the van to use it when we got to our destination or returned home, the power steering pump would make a noise for about 50 to 100 miles. Normally it was about to straighten out when I loaded it back up to bring it home. I've had it checked out and no one has been able to tell me why it did what it did. I towed it with the wheels locked by the key, I even tried towing it with the wheels unlocked trying to figure it out.
I tow a Jeep Liberty and have been for a couple of years. I enjoy flat towing much more than using a dolly but you have to do what's best for you.
I'm starting to explore upgrading the Liberty to something more comfortable for me to drive. Ethel loves it but I don't enjoy driving it to far. If someone needs a 2006 Liberty 4wh drive set up to tow with about 48,000 miles on it, let me know. It's nothing fancy. It has cloth seats, A/C, CD, P/W & locks, and all the other normal factory stuff. I'm a fanatic about maintenance and it's sitting on low mileage 30" tires. It's about a medium blue in color. I live in South Louisiana.
Good luck to you!
