A Question about building a trailer frame...

Was going for a Dinnete trailer but was given a truck slide-in camper and being a very cheap guy that I am, going to that on a trailer.
I need a 6'x14' flatbed trailer that will hold the camper in the back part and will hold my atv across the front. the gross of the two is about 2600lbs (fully load camper=1600 and the buggie=1000).
I would like to trailer to less than 1500 lbs empty and with a loaded tongue weight to be no more than 400lbs.
I just dont know which metal stock to use ie.. 3x2 box or 2.5 angle iron. Also not sure on the axle(s) yet, I perfer the older spring type.
Can ya'll help me.
Thanks,
Roger
