Specs. 2006 E450 6.0/5R110, 102k miles, ~14' box, 14k GVWR, Jacksonville, Tx [October-ish, 2011] v2.0, Long story short .... I got it back. This was going to be the super RV, then I had a stroke. I sold it, buddy bought it, then he died (BigJuggy), then I bought it back. (wife) Old thread. E450 RV / Tow Rig ..... I've changed the plans a tiny bit, to address my older self, new hips, no glasses, different outlook, etc... Basically is going to be the same but I decided to have an automatic and no 4x4. I'm doing the interior difference and I'm planning on spending a wee bit more money (over time). Things like add a bed that raises up to the ceiling... A separate bathroom... A couple of chairs, not just a bench... Yes, it will have the 5.9 Cummins but I have add a Allison 6 speed transmission. . Ill have more of those in a while. . In case some of you want to read about the whole story.....
