We had a 2004 Chev 2500hd 4X4 Diesel that the manual and dealer said could NOT be flat towed as it had the electric push button 4X4 selection.
We sold it and bought a 2008 Honda CRV and installed the blu-ox base plate and tow bar. I installed the Invisibrake and light conversion.
The Honda weighs 1/2 that of the PU. You hardly know that it is back there. Of course I keep my rear camera on to watch it.
Make sure that your pickup can be towed. The Manual is very clear about if it can or can't be towed.
