If only flat-towing were an option!

[Stannventures]

I am a complete Grenadier wannabe. I test drove it this weekend and fell in love with it! I asked the salesperson about flat-towing, and he said I think people have done that. The problem is the internet says different. I currently flat-tow my Jeep Wrangler behind my RV and would gladly transition to the Grenadier if it could be flat-towed, but as far as I know, it cannot. The only possibility I found on the internet was:

"The Superior Driveline Drive Shaft Disconnect (DSC)​

The Superior Driveline Drive Shaft Disconnect (DSC) allows RV’ers to tow their rear-wheel and four-wheel drive automatic transmission vehicles behind their motor homes with all four wheels on the ground – worry-free."​

They do not offer a pre-configured setup for the Grenadier, but they do some custom work as well, so I sent them an email. No response yet. Based on my understanding of the Grenadier set-up, I think it would require two of these devices to isolate the two drivelines, dunno for certain.

My post is to see if anyone has tried this approach. Have you?

Since the Grenadier has full-time 4wd you'd need disconnects in both front and rear driveshafts. The driveshafts on the Grenadier also have more complex joints than those in the link.

Technically it is a feasible solution but it probably isn't practical. It might be easier to tow the RV with the Grenadier!

Piece of cake to unbolt front and rear driveshafts from the diff pinion yokes and hang them up. Just need to be careful not to pinch the boots while moving the CV joints around.
Easy access under the truck, a 5-minute job for each end with a 1/4" impact driver.
I flat-towed a Range Rover Classic behind another RRC for 200 miles like that - the only difference is that unbolting the U-joints from the axles took a lot longer time (IYKYK).
