On a Sunrader what engine would you recommend with an auto trans especially on a 21 footer. I noticed TurboGregg has the turbo. I've also followed his posting on the difference between the turbo and v-6. Does this mean I should steer away from the 4 cylinder? If I understand TurboGregg right v-6 first, turbo 2nd. TurboGregg, any thoughts on the intriguing Lexus V-8 and auto tranny swap? Thanks for your help.
