Thanks for the feedback, sorry should have said my truck is auto.
Im a Kiwi from New Zealand and most of our vehicles 75% down there are manuals or were up until 15 years ago, now its likely 50/50
Im a mechanic by trade, but your terminolgy here is a little different to ours.
Causing some confusion, also the dealers were very conflicted on their opinions.
If my truck was manual I would not even be asking as ANY manual trans vehicle can be tow'd in Neutral day and night as fast and as long as you like.
The gears are not rotating and nore is the input shaft of the gear box etc, you may get a small amount of drive shaft rotation caused by friction within the diff gears, but this no issue.
Just thought id mention that as some folk seem to think towing a manual requires certain prep, which is false.
Just to be really safe and because I dont feel like spending a weekend changing a transmission or crawling under to disconnect the dribble shaft each time I want to tow,
I think we will invest in one of the shaft disconnect units " thanks for that link" thats a handy piece of kit.
Back in NZ we had a Jeep Cherokee auto which towed great behind our RV there, as Jeep were smart enough to equip them with a tow mode in the transfer set up, as most of you are aware.
However I didnt want another Jeep and Jeeps a really pricey here, even for older units.
So the D/S disconnect is ideal.
Thanks again everyone
