  "I want to encourage others to become forum members. Joining these forums is free, and it is very easy to become a member...I'm getting reliable information, professional advice, money saving tips, safety recommendations and, for the first time, practical and proven solutions that don't always involve spending a fortune. And when it's time to buy parts and aftermarket items, I'm making better choices and have confidence that the upgrades and accessories will actually work!...Join us, you'll be doing yourself a huge favor, and we'd like your participation!"—Posted by Member 'Biggman100'

     "I first read Moses Ludel's writings when I bought his Jeep Owner's Bible years ago. I joined the forums to solicit advice on my cylinder #1 misfire. My mechanic advised replacing the motor due to the 250k mileage. Moses started with fundamentals, rather than part swaps. And other folks here have chimed in with additional advice. The misfire topic is getting a lot of views, so I assume there's a bunch of other TJ owners whose Jeep 4x4s are aging and need some attention. I agree with Biggman100, joining these forums and posting a question is going to get you help and educate the rest of us."—JJ_Jeep, Forum Member since June 8, 2013
