Possible? Yes. A good idea? Not really, since not all welding can be accomplished or helped by all that. To me as a welder (not by trade), a 110v welder not even practical for 1/4", let alone 3/8".
My first wlder was a Hobart 135 amp 110v welder and it did fine on smaller pieces but once I had to weld some large surface area pieces of 3/16", it couldn't generate enough heat to properly penetrate the steel while welding. The thickness wasn't the issue, it was the size of the piece which was dissipating (sinking) heat faster thah my 110v welder could generate it. Bevelling and multiple passes would't have worked for what I was welding either so I sold that welder and bought a Miller 180 220v welder and never looked back.
Bobjenkins, I ended up with Miller's 180 Autoset and it does everything I want it to. Their 211 is sure sweet though and would be a good choice if you want it to be portable so you can plug it in to 110v when 220v isn't available. But if you plan to keep it at home and can give it a 220v outlet, I think the less expensive 180 Autoset would do everything where a Jeep is concerned.
By the way, that Autoset feature which eliminates having to set the wire feed speed, sure is a nice feature that makes getting a good weld a lot easier. Autoset cuts the variables you have to set by 50%, all you have to do with it is dial in the voltage according to the thickness of what you're welding. Sweet!
P.S. Here's Miller's webpage that shows both the 211 and 180. http://www.millerwelds.com/products/mig/onephase.php
