We no longer do repairs here, for the time being until we find someone as handy as Brian who has gone on to accept a 'real job' with benefits and insurance and all of that good stuff.

Magnum trailers, however, can do horse trailer repairs here in Austin.  512-258-4101.

But, for major Brenderup repairs, call ASAP Trailer Services & Supply, 16330 FM 2920, Tomball, Texas.   281-351-7855

Or call the Brenderup plant in Midland, 800-745-1307 .

For trailer hitch installation, I have had very good luck with:

http://www.texashitch.com/texashitchhome.html   They are here in Austin and also in San Antonio.   Call ahead and they can usually do the work for you that day.   Remember, 2" ball and 17 to 19 inches from the ground.  

Also, Brenderups normally come with a 6 pin electrical hookup, but, you can have a 4 pin if you order your Brenderup from the factory.   Otherwise, I've found that Walmart has a pretty good selection of adapters.
