Looking throught the JFTR's, I came across this regarding what could be accounted for in the household goods weight:
HOUSEHOLD GOODS (HHG). Items (except those listed in 2 and 3) associated with the home and all personal effects (see NOTE 1) belonging to a member and dependents on the effective date (see NOTE 2) of the member's PCS or TDY order that legally may be accepted and transported by an authorized commercial transporter.
NOTE 1: See par. U5310-E for articles involving weight additives.
NOTE 2: HHG acquired after the effective date of the order but before entering an IPCOT may be shipped when par. U5370-I1b or U5370-I2 applies.
A. HHG also include:
1. PBP&E needed and not needed for the performance of official duties at the next or a later destination. PBP&E that are needed are not calculated in the member’s weight
allowance and therefore must be weighed separately and identified on the origin inventory as PBP&E.;
2. Spare POV parts (see the definition in this Appendix) and a pickup tailgate when removed;
Change 252
A1-15 12/1/07
3. Integral or attached vehicle parts that must be removed due to their high vulnerability to pilferage or damage (e.g., seats, tops, winch, spare tires, portable auxiliary gasoline
can(s), CD players, GPS systems, and miscellaneous associated hardware);
4. Consumable goods for members ordered to locations listed in Appendix F;
5. A vehicle other than a POV (such as a motorcycle, moped, hang glider, golf cart or snowmobile (and/or the associated trailer));
6. A boat or personal watercraft (e.g., a jet ski) 14 or more feet (and/or the associated trailer); and
7. Ultralight vehicles (defined in 14 CFR §103 as being single occupant; for recreation or sport purposes; weighing less than 155 pounds if un-powered or less than 254 pounds if
powered; having a fuel capacity NTE 5 gallons; airspeed NTE 55 knots; and power-off stall speed NTE 24 knots).
8. A utility trailer, with or without a tilt bed, with a single axle, and an overall length of no more than 12 feet (from rear to trailer hitch), and no wider than 8 feet (outside tire to
outside tire). Side rails/body no higher than 28 inches (unless detachable) and ramp/gate for the utility trailer no higher than 4 feet (unless detachable).

So it looks like Bluto's motorcycle trailer is all good, as long as it has a motorcycle in it, but my general purpose enclosed utility trailer isn't. Too bad I don't have a moped to throw in it and make it a trailer for my moped....
Thanks
