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.

Spillar hitches, however, can do horse trailer repairs here in Austin. 
2701 South Congress, Austin, 78704, 512-444-3227.

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:

Again, Spillar hitch, above (512-444-3227)
OR
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 18 to 19 inches from the ground.  

Also, Brenderups now come with a 7 pin electrical hookup.   Trailers before 2009 were a 6 pin, fyi.   I've found that Walmart has a pretty good selection of adapters if you need one.   Remember, you need a higher number of pins on the towing vehicle than the towed trailer for the adaptor to work.   Also, if you would rather your new trailer have a different type (4 or 6 for instance), let us know and they can make your trailer as you wish.
