I have complete smoke system kits customized for every model of RV. Some of these tanks are “hidden” and take up little or no baggage space. Any tank can be made quick removable.
These complete kits feature beautifully welded aluminum tanks, a real, honest to goodness oil pump, not a converted fuel pump, and 2 (not 1) of the best oil injectors on planet earth. You can also get any individual part you may need. Complete kits come with written instructions and photos and I am always ready to answer any questions by email or telephone. Complete kits start at $760. depending on what tank you need. Tank capacity can be anywhere from 3 gallons to 8 gallons. I can also make custom tanks for other airplanes.
My own brand of premium smoke oil (Snake Oil) is available in 5 gallons or 55 gallon barrels. 5 gal is $65. and a barrel is $475. plus shipping and a barrel ships almost as cheap as 5 gallons. That is about a 2 year supply for most of us fun fliers. The price of smoke oil will be increasing Jan 1, 2019.

Just phone or email if you have any questions, I love to gab about airplanes.
