Re: GAS or DIESEL... What's this girl to do? John, check out Gulf Streams from GTS (Grandview Trailer Sales) in Virgina. He is a straight shooter. Don't know if he can help you out with a toyhauler, but he has good advice. Maybe you can include a trip to Virgina after you get a (GAG) V-10. He will probably respond to this thread or you can e-mail him on this forum. Its been 12 years since I retired. Time do fly. Good luck on the truck and RV.
