get a non commercial class A with doubles/tripples endorsement.
this way you can legally tow your fifthwheel and one trailer down the hwys.
there are fed and states laws dealing with width. length, and weights..
but with a class A as stated a ove you are good to go in ALL 50 states.
---pending local--- hazard restrictions.
but your pu MUST have the capibalty of pulling the total weight. and have the breaking ability. other than this it is up to axle length limits. and total bumper to bumper length.
this is in a nut shell.
BUT under NO reason can you do tripples with a pu or rv set up.
