Yup, I’ve towed my Choptop on a tow bar and a tow dolly hundreds of miles now. Throw the T-case in neutral and have at it. You’ll want the steering unlocked though flat towing on a tow bar though, it follows the tow vehicle better that way. If you’re worried about having the key on and draining the battery, just disconnect the battery.
Also, double check the T-case is in neutral. I recently pulled the Choptop and had it sitting for a night with the T-case in gear so it wouldn’t want to roll anywhere. Forgot to put it back in Neutral the next day and tried pulling it. My F-150 dragged it but wasn’t real happy about it and it quickly dawned on me what I did. I was essentially trying to pull start a blown up motor and over-reving the snot out of it (doing 35 in first, lol). Good thing it was a junk motor, lol
