The new Rocketfin.com model book is out, Building Scale Jeep Models: Modifying and Assembling Jeep & 4X4 Model Kits.
There aren't many Jeep kits out there, but the AMT offerings are still around, such as the Hogan's Jeep, and the Revell Rubicon has been a hit as well. Read about assembling these models, as well as a Tamiya Wrangler, and the military MB and Bantam Jeeps. No small scale stuff here either, these are all 1/20,1/24, and 1/25 scale. You know, the scale us car guys like. You can do quite a lot with these Jeep kits if you don't mind modifying them (isn't that what a 4X4 is for?), and if you do build 4X4 kits, from trucks to whatever, you should enjoy this book, especially written for those projects.
