First off, welcome to the boards from a fellow Texan.

Of the brands you listed, my personal preference would be the 4 Star or the Elite. They are both better quality trailers than the others (in my opinion).

As far as features, here's a few things I decided on before I ordered my trailer.

Windows - good ventilation in Texas is a must. However, I have seen too many trailers with wasp nests, bird nests, or mice in them and chew through the wiring if the trailer is open (i.e. Stock Trailer). I preferred a closed in trailer for that reason. Also, the plexi windows do allow a lot of ventilation but give you the problem of having to store the plexi somewhere and they are a pain to take out and put back in. You will find that you either leave the plexi out or in because of the hassle. I got drop down windows on the head and bus windows on the rear with 2 air vents in the hgorse compartment. They get great circulation and no problems at all !!

Collapsable Reat Tack - Although this would be handy if you plan on using your trailer to haul things, remember that whenever you wash your trailer out or your horse urinates, guess where the water runs !!! You have to completely empty everything off the floor in your tack area before you hose the trailer out and wash all the stuff off if your horse urinates. There are some great opinions on windows and rear tacks on the "Trailer options" post - great thought from many different people.

I am pulling a 4 Star 2H Slant GN (aluminum) with DR (21' total length) with my 1/2 ton pick-up and it pulls great with 2 horses in it. You would be better off looking for a good QUALITY used trailer that will meet your needs and last you a long time than getting a new trailer that won't pull as easily or won't last as long.

Good luck in your search. If you are in the Dallas - Ft. Worth area, I can give you suggestions of different dealers I contacted that were very good to work with and extremely helpful in getting me information and contacting me if they had a trailer come in.

I had some conversations with Gulf Coast 4 Star in Belton (near Waco) and they were great. I'm guessing that would be about an hour or hour and a half for you - straight north on I-35. Their phone # is 254-939-8100 and you can see their inventory on their web site http://www.gulfcoast4star.com/ .

I bought mine from Wayne Hodges Trailers in Weatherford and they have been wonderful. Their web site is http://www.waynehodgestrailers.com/ .

If you are looking at Sundowner, the dealer here is also very good and sells Sundowner, Hart, and CM (I think). They list inventory on http://www.sundowneroftexas.com/ .

A friend of mine has bought 2 trailers from Durham Trailer Ranch and they sell Bloomer, Elite, Classic, and Titan. Their web site is http://www.durhamtrailers.com/ .

There's also a dealer in the Waco area that sells Platinum Coach trailers (very impressive trailer) but I can't remember their name. I'll post it if I can find it.

Good luck. Feel free to PM me if you have any other questions.
