The least of my worries would be the engine. It is an inline 6 cyclinder heavy duty GM motor. I'm not much of a GM man, but this is one hek of a motor! We have a few of them and with regular maintainence you shouldn't have any problem with it. As with any engine though, look it over thouroughly for any leaks or problems and make sure it runs good. Only common problem is exhaust manifold cracking. She does like to drink but it should last a couple of full days of running. let me know what you do or e-mail me with other questions if necessary.
