This is the tank I have:
Square Transfer Tank - Brite-Tread
I believe I paid about $350-400 for it, but don't remember where I ordered from. They also have steel tanks for a lower price. Tractor Supply sells many of these tanks in different sizes and styles.
Mine is bolted to a heavy duty pallet which I strap down on my truck or trailer.
The weight is minor -- well under the lift capacity of my L3200 which can lift around 1200# or so.
Find me something cheaper, I check that tank, I do like it but $570.00 is about $500.00 more than I can afford. Sounds like your L3200 has more grunt then my L3400, what's up with that.
