Diesel Heater??

[bettyford]

I'm going to install a diesel heater myself. I would love some feedback on which one you all think is best and why.

1. Where to buy it?

2. Should I use a separate tank (gravity feed)or should I tap into my van tank and add pump? Why?

3. Should I use something else.

4 . Problems????

I know this has been talked about on other threads so thanks for answering my questions.

Thanks
Ron
