Recently purchased a 2017 144” high roof that will be towed behind a 40’ Alfa see ya .... Will be driving sprinter down to Yuma AZ to meet up with Southwest driveline to have them install the quick disconnect .... then I will rally up to Vancouver WA to have the Roadmaster team use the rig as a template to update baseplate for newer models .... I have towed a 4x4 Toyota Tundra with shell and am now towinga 4x4 Tacoma with shell now... the 2017 sprinter is 2wd.... wanted a 4x4 but with a 2 piece drive shaft , it is already difficult enough to have quick disconnect installed then to also add 4x4 issues... keeping the Tacoma so will still have a 4x4 and can tow it if needed ...
