Funny you should bring the hitch lock up. I was just getting ready to do an internet search for a lock. I have returned two already for my White Hawk. The hitch seems to be very large. If you find one or the Trimax works, please share. As far as temp control goes, we just got back from our first trip out. The temps were in the high 90's. At first it seemed like the trailer would never cool off. It even tripped the breaker. After I reset the breaker, no more problems and the AC cooled things down to the point we had to raise the temp on the thermostat. It stayed pleasent inside the rest of the trip. We did order ours with the upgraded 15,000 BTU AC unit. This may have helped. We have a couple first trip wrinkles. First and most obvious is on another thread I started concerning my popping axles. They seem to have settled down a little, but still frequent. I am calling the dealer tomorrow, before I tow it back. The second I noticed today while cleaning it up. I had the radio on and the outdoor speakers are shorting in and out. I removed the radio and checked connections, but they were all good. I think I may need a new radio.
