We used to pull behind our 5er but we bought a large Jayco tt so I could have my truck bed back. I much prefer towing the travel trailer and hauling our Rhino in the truck bed. Most states West of the Mississippi allow doubble towing. Washington and Oregon are still living in the dark ages.
2011 Eagle 330RLTS with just about every option.
2017 Silverado 1500 4x4 5.3 with tow package. (no, we don't tow the Jayco with it.)
2018 Surveyor 265RLDS well equipped.
Life in the slow lane is still life.
