I agree with the advise to check with the officials at the base you are PCSing from. They are the experts. But one word of advice from an old CSM. As this is a partial DITY move, empty your TT completely of all personal belongings before weighing empty. I would have a full load of propane and fresh water as that is included in the empty weight. Now load all you personal items back it along with any cargo you can safely carry. All those pots, pans, clothes, lines etc normally kept in the TT are part of you HHG and should not be included in the empty weight.
