Buyer's guides
Questions buyers ask
- What is the difference between a vacuum truck and a combo unit?
- A vacuum truck pulls liquid or slurry into a tank. A combination truck, usually called a combo unit, adds a high pressure water pump and hose reel so it can jet a sewer line and vacuum the debris in one pass. A hydrovac uses water to dig and vacuums up the spoil.
- What should I check on a used tank?
- Ask for the last ultrasonic thickness test or tank inspection, look for pitting inside the manway, check the sight glass, and open every valve. A tank that holds vacuum overnight is a good sign.
- Do I need a CDL for a vacuum truck?
- Almost always. Most vacuum trucks are over 26,001 lb GVWR, which requires a Class B or A license. Some small slide-in units on a one-ton chassis stay under the limit.
- Can I finance a used vacuum truck bought from a private seller?
- Yes, most equipment lenders will fund a private-party purchase with a bill of sale and title. Have financing approved before you meet the seller.
