I just bought a 2000 jeep wrangler se. It's a automatic. I bought it for my hunting trips. I need a car that I can take on the trails when I'm big game hunting n pull a trailer behind for my dog n his kennel when I'm bird hunting. I have lots of questions about modifying. 1st of all, will I have a problem towing a trailer that's a 1k pounds? The manuel says that it can tow up to 1k pounds. N second....if I put 31 inch tires on the jeep, will I have to change the gear differnical on it? Thanx!!
