I want to use this in rv (had one in last rv), turn off when traveling (would never mount horizontally for vibrational harm) any precautions to take?

I have mine mounted horizontally for one year and so far so good

Does the unit have a warranty?

Yes, please take the user manual in the Technical Specification part as a reference.

Is it okay to use this with an extension cord?

for the electronic ballast? It would be okay.

If I cycle this product on and off to match the power cycle of my pump for the holding tank, will it shorten the life of the bulb?

The on/off times should last over 10,000 times for the uv bulb. Do not over that, and it would work fine.
