I agree with Ultra... No problems... I used to do it once a week... The ATIS will tell you whether or not to use your XPNDR while taxiing... If your picking up pax or dropping them off for flights out of DFW the FBO is very helpful with transportation... Plan on long taxi and sometimes long waits for take off.. Have pen and paper ready for taxi instructions, don't get the Y and Z bridges confused...You will usually land on one side of the airport and depart on the onther... GA is on the west side right off the Bravo (B) bridge, I think, which is on the south side of the field.. Have fun...
