I have a Karr Kaddy SS w/surge and I really like it. The braking self adjusts with varying weight's. The only negative is it's a little heavy and cost a little more. But factor in you have no need for a controller, can use it on other vehicles (without a controller) and it's compact storage-it's a winner.

We went through this decision process about one year ago. We ended up buying a Mastertow 80HDS (surge brakes). I didn't want to add a controller and worry about the right setting, etc. The surge system adds about 90 lbs. to the weight of the trailer but it works great. I added a trailer jack to make it easier to handle, and that was the best $20 I have ever spent.

I believe our dolly cost about $1,500 and I bought a spare which I carry in the trunk of our toad. We have towed it now for about 7,000 miles with not a single problem.

Here is a picture of our rig and tow dolly. Note, the trailer jack was installed after this photo was taken.

Surge brake Pros: X2 what wardy said
No controller needed.
Self adjusting
Use on other vehicles

Surge brake cons:
Hyd. lines seem to vibrate and crack
Can't adjust the braking pressure

Electric brake pros:
You can adjust braking pressure
A little easier to work on

Electric brake cons:
Difficult to feel how much power to apply when behind a 20K lb MH
Have to install a brake controller.
Whatever vehicle pulls it will have to have a contoller

IMO, get the surge brake.

Hi njoylife,
I have a dolly with surge brakes. It works as advertised and I would make the same purchase again. Best I know, the only disadvantage with surge brakes is when on a long steep down hill grade, the surge brakes will be on all the way down the hill. Since I do not plan to take the dolly to the dolly west of the Mississippi, this is not a problem for me.

I prefer electric brakes. I've had trailers with both and as they get older the surge brakes seem to have more problems. They need the same maintenance as the hydraulic brakes on your car, including periodic fluid changes and shoe adjustment. They have a tendency to apply and release when going over rough terrain. They are only proportional once the load overcomes the initial spring pressure.

While it's true that electric brakes require a controller almost every truck and motorhome since 1999 has been prewired from the factory. I've used the same Tekonsha Prodigy controller on my 1999 Ford Expedition, 2001 Winnebago Adventurer and 2010 Ford Expedition. It's plug and play taking all of 2 minutes to move it from one vehicle to another.
Electric brakes are truely proportional in that the controller can be set for the load on the trailer/dolly rather than a preset spring pressure in the coupler. There is no fluid to change or cylinders to rebuild as age sets in. We currently have a 10,000 lb trailer and a 3,500 lb tow dolly both with electric brakes. The trailer is about 15 years old and the dolly is 10 years old. Both are used regularly and neither has had any problems I have no desire to go back to surge brakes.
