How many of us are there? Owners of Dodge based RV's?

Aftermarket electronic throttle body injection (TBI) conversion?
Sounds very interesting but i think it's not cheap. Do you have more informations about it? What i need is a bullet proof engine for travelling. This car is exotic here in Europe and I have to solve every problem on my own.
I am very glad, that i found this forum and you answer all my questions :-)
