You have a98 jeep Cherokee sport with auto trans and 4.0 6 can you flat tow this unit?

Yes, if it's a 4 x 4. I towed one behind my motorhome all over the US. Just leave transmission in park or neutral and place transfer case in neutral. I always did this with engine running, put transfer case in neutral, then checked to make sure by placing trasmission in drive to make sure transfer case was in neutral, then placed transmission into neutral and shut off engine. Don't lock steering wheel ! Leave key in lock and engine off, but unlocked, as front wheels need to be free to turn. Remember you can,t backup much, as wheel will turn hard over after a few feet in reverse.
