Thanks for all the info. TT is rated at 4365 dry weight, so it is pushing the limit with gear, although I haven't put anything in the TV or TT. It was all set up by the TT dealer. I've called them, they told me that I needed different tires. One fellow told me it was because I was new to pulling (which I agree) but I would rather be comfortable with towing then scared sh*tless when towing. I will have to see who the manufacturer is for the WD hitch. Never got over 60MPH. Way too scared to go any faster. :)
