OK I know it's a can of worms, but looking on line I see tow bars from $200 to over $1000. Which one will do the job? 03 Wrangler, under 5klb's, Which hitch, from who?
Depending on your front bumper you may not need a baseplate. My previous Jeep was pre-drilled for tow eyes. You can get new bolt-on replacement front bumpers that are ready to go.
