When I had the M816 insured (before the engine issue) with Progressive my cost was $630.00 every six months. I had a farm tag on it and the agent told me if I had an accident while towing anything on a public road that my policy would be voided...even if I was towing my own stuff. Towing insurance is very high since you are considered commercial.
As useful as mine is around the yard it is a money pit......I have another engine for it but I will prob not put it back on the road as there is no way to break even on it.
I'll just use it around the Motor Pool for lifting and moving stuff.
Concerning the care and feeding of 5 ton wreckers:
(1) A lot of stuff, filters and such, can be crossed or replaced with civy stuff.
(2) A lot of stuff, mechanical and hydrolic stuff, cannot be and will cost you out the wazoo when it breaks. One hose on the crane set me back over $100.00 and there are a lot of them.
(3) It cost me over $100.00 bucks to change the oil and filter (using Rotella).
(4) The big cannister fuel filter cartridge cost over $50.00 at NAPA. I replaced mine with a spin on with drain cock on it for $85.00
(5) The big hydrolic tank holds about 50 gals of oil...if you blow the right hose all of it will end up on the ground.
(6) The 250 Cummins is a good engine but the wrecker weighs about 36,000 dry...it is slow on the road....54 MPH is about tops...that's downhill with a strong tail wind.
(7) At road speed it will suck the bottom out of the fuel tank....prob 4-6 MPG going off a cliff in neutral. It also sucks fuel when using the crane.....you have to idle it up to around 1200 RPM to make everything work right.
If they sit for a while the seals on the fuel tank selector valve (located next to the drivers seat) dry out and will allow air into the sytem....causing starting issues and generally making you crazy while trying to crank it.
I bypassed mine and run off the left tank only.
In spite of the above I love the big beast (I call it Hugh G. Rection) and will prob keep it in the stable.
I always wanted one.....since I was a young Private in the army....now I have one.
Be careful what you wish for
