I cannot find my brochure right now, I hope someone can help... It does seem awfully small, really, especially towing my 24ft trailer!...

Yes, with the trailer, I get about 12 mpg, that tank is annoyingly small! My truck has a TBI350 and TH700R4.

Could be the final gearing, or I need to spend $$ for a 700R. | | | | | Joined: Dec 2001 Posts: 14,522 Moderator: Welcome Centre, Southern Bolters, Legion Hall | | Moderator: Welcome Centre, Southern Bolters, Legion Hall Joined: Dec 2001 Posts: 14,522 | Tank Volume? To figure gallons in a tank multiply LxWxH X .004329 = gallons. | | |
