Detroit locker up front and ARB in back. Both axles are D44's and the front has hubs.
Hubs in "free", ARB unlocked, T-case in neutral, tranny in fifth. No issues with the jeep while towing, in fact, it *towed* fine. But I have to admit, a trailer responds better to towing. Brakes, backing, and emergency maneuvers are better handled with a trailer. I had a large box fall out a vehicle two cars in front of me. The car ahead dodged it easily, me flat-towing the jeep with my 1-ton pickup was not so pretty. All kinds of "wag the dog" excitement for a few seconds.
If I had the option, I'd trailer it. But flat towing is fine from the jeep's perspective, as long as you read your manual. As for your aftermarket parts, call each manufacturer and see what they say. Pays to be sure.
