F150 Ecoboost towing two trailers
 

I have 2011 F150 Ecoboost with the max tow package 3.73 gears
My original plan was to buy a 25ft toyhauler RV pull Trailer and haul my polaris ranger in it, the only think i hate putting a muddy machine in a trailer and then cleaning it out. I have been thinking lately about getting a light weight fifth wheel about 22feet in length and pulling a small 8ft aluminum utility trailer behind it with my Ranger on it. My Ranger with Gas weights about 1250lbs, the alumunum trailers are about 400lbs. In total weight i will not be over 7000lbs fully loaded.
Anyone pulling simular setups on this? just want you opionions if you are

I don't think you will have any issues as long as that is legal in your state and don't have to reverse.

X2 check your state it probably has a total length limit so as long as you are within that you should be ok. I have a toy hauler and to avoid bringing in the mud I went and bought a tarpthat fits inside to park on. Then when you unload just roll up the tarp and take the dirt back outside to dump it. It has worked well.
