HI All, I am looking into buying a used roll off truck because it seems to be the most versatile truck one can buy (can switch bodies for different uses).....My needs are somewhat basic for now (basically I want to tow my Case 680 Backhoe (approx 17000 lbs) as needed, and I want to be able to mount a 1500 Gallon Hydroseeder on the truck also as needed (I will use a modified Roll off container or setup so I can swap off bodies as needed).....Otherwise, the truck may be used as a mulch/trash hauler, or maybe even a moving truck at times if outfitted with an enclosed container.....or maybe even be used as an actual roll off truck for renting dumpsters....Hmmmm imagine that! Anyways, I don't want to spend a lot of $$ on the unit itself (probably less than 20 K)....I don't mind an older truck but mechanically it must be good. I have read and read but I was wondering what you would recommend in terms of truck brand and equipment the truck would be outfitted with. I am thinking Manual tranny is a must (probably at least 6 speeds....prefer not to have to mess with the trouble prone 2 speed rear), budds instead of 5 spokes, air brakes, AC would be a plus, debating about GVWR....I am thinking heavy single axle would be OK but live tandems may be better BUT am a little concerned about the added tire wear (is it like wearing the rear tires on a tandem trailer when turning?...maybe an air lift pony axle but haven't seen too many roll off trucks with this ....the thought of wearing tires out quickly makes me a little paranoid about tandems......Debating about engine choice....probably bigger is better (obviously diesel)...Saw a truck with an L10 Is that good?...not too familiar with the bigger diesels....Basically probably Cummins or Cat huh? Basically I want a workhorse of a truck that is reliable and relatively inexpensive to repair. Thanks for any ideas and opinions on this....Go crazy with suggestions on how I can accomplish my goals! Thanks again!
