Fellow OGF Members, I'm about to replace my 94 Silverado, 5.3L, V8 to continue towing my 18ft Trophy. I test drove an "08 Chev, 4.8L today. Is it adequate for my towing needs, or should I look into the 5.3L. Don't really care about high gas. That's part of life. I just want a confident ride, & best engine for the job . Thanks in advance for replies.
