Re: hitch and tow bar choices advice?
an equalizer hitch is important to have if the trailer is heavy in comparison to the tow vehicle, if you're towing a 2500 # rabbit on a 1000# trailer with a 14,000# bus a regular non equalizer hitch is sufficient. look at other medium duty trucks and the trailers that they pull, (dump truck with a trailer and small dozer or backhoe) no equalizer and usually a pintle type hitch.
my choice for a good pulling trailer is a minimum of 5'of tongue length, you need 4' just to keep then trailer bed from touching the bus in a tight corner, the axle should be behind the center of the bed, the axle usually ends up about 2/3 of the way back of the total length, 5' tongue,+ 1/2 of 12' bed=6' + 6', total length=17' axle centerline is 11' back, rabbit has a 9' wheelbase so you have 3 feet to adjust for balance/tongue weight. build the bed 14 or 16' long to make it more user friendly with other vehicles.
tilt bed, just like it sounds, make the tongue extend back to just in front of the axle and install it in pivots, so that the bed can tilt for loading, the front of the bed will be fastened to the tongue with a locking mechanism when loaded, use a trailer tongue jack, between the tongue and bed, to tilt the trailer bed.
install stake pockets so you can put sides on if desired, they are also handy for tiedown points.
it is safe to assume that mobile home axles are usually 6k axles.
