Looking for opinions on tow dollys

Specifically ones with electric brakes. I've successfully flat-towed my MJ with the CRD Liberty and it's not something I'd like to do again. A full-on trailer with my MJ on top is too heavy for the Libby to handle. So I'm thinking about a tow dolly with brakes. The Libby is already set up with the 7-pin connector. I've seen what the U-haul near me tries to rent out and I've no inclination to try their dollies. For the record though, U-haul's website gives the CRD the thumbs up for hauling an MJ (stock one at least )
Opinions? Anyone here used a dolly with brakes? In my head it'll make a significant difference, but can't say for sure without trying it.
Thanks,
--Pete

should make a huge difference in stopping at least.

Stability wont be much improved, the libby will still get pushed around quite a bit.

Obv. acceleration would still suck.

Well, acceleration on the freeway leaves much to be desired, but that little diesel takes off with authority from a stop.

Get a truck.

A tow dolly won't make your Liberty a truck.

I believe Pete is trying to work within a budget here...

I uderstand that.

However, I have known several people who thought they could tow with Libbys, and it never ended up well. Towing isn't something to screw around with. A good tow dolly with brakes is close to a grand, and I would rather tow with a $1200 truck than a Libby with a $1200 dolly.

Sell the libby, buy a truck & trailer. Don't waste your money on a dolly.

I gotta agree with Cooter & Whitey.. If it was something small like a sammi or flattie, I'd think different, but with a good tow dolly, thats a 5000 lb oad, which is a recipe for problems.

Remember, stuff happens. fuses blow, trailer brakes fail, tires blow, axles break, snow and rain happen, people cut you off, etc. Sure, it'll tow on a clear sunny day with no problems, but... stuff happens.

Besides, thats a large load for 160 hp. Being underpowered is danrgerous on the freeway, especially on ramps.

Thanks for the opinions guys. I know that a fullsize truck would be ideal, but I have to work within the constraints life has given me. The liberty is my dad's, not mine. There's no fullsize truck in my future unless I land some awesome job with my new IE degree and have money coming out my wazoo. The Libby has 300 ft-lbs available and is rated for 5000 lbs. I've towed 3k+ lb trailers many times before and my biggest concern has been with braking. While towing a load this little Jeep could easily beat my Uncle's F-150 (with the 4.6) in a drag race or passing on the freeway, but I have to keep a good space in front of me on the road. I know electric-braked dollys exist int he world and was hoping to find someone that owned one so I could get some first-hand opinions on its performance.

You can get a brake actuator that will apply the brakes on the vehicle being towed. It might actually be cheaper and a safer alternative to a tow dolly. Those brake actuators are available through any reputable RV Dealer that sells motorhomes.

Previous posters have mentioned that a good tow dolly will cost you $1200.00(at least). You would be better off spending that money on an old beater truck, it would be much safer.

I am an RV dealer, I only sell towables, but I can tell you the problem with towing with the Liberty CDR isn't power, but lack of wheelbase for stable towing. I could easily put a 27ft lightweight travel trailer that weighs around 4200 lbs behind a Liberty and be within it's rated towing capacity. This would create a serious case of the tail wagging the dog.

This is the very reason that short TJs with a 4.0 are only rated to tow 2000 pounds while the same drivetrain in an XJ can rate you up to 5000 pounds. Unlimited TJs tow up to 3500 pounds, because of the stretch in wheelbase.

Hopefully this gives you some helpful information.

Yes, I appreciate all the good words too. I've towed the MJ with the KJ before and have a first-hand understanding of wag-the-dog. The front end of the MJ likes to follow grooves in the pavement and the bad track bar (which will be fixed before I drag that thing anywhere anymore) accentuated it. But it's not so bad as to be life threatening and I never exceed 55 or 60 mph and just follow the big rigs in the right lane. I'm curious to see if the dolly would work better than flat-towing. Would the wagging-of-the-dog get better or worse? How much braking power does a tow dolly have?
