My brother has two hook lift trucks, both with the Stellar Hooklift systems. One is a 2004 GMC 4500 crew cab, Duramax/allison and the other is a 1999 International 4900 crew cab 4x4, DT466/7 speed/33,000lb gvw, air brakes.
The GMC is questionable in handling this kind of system. It has 3 or 4 extra leaves per side on the rear and 2 extra leaves per side on the front. The engine has a 30-40hp chip in it and an egt gauge, otherwise the whole truck is bone stock. The truck is nearly at its posted gvw with an empty can on it. It routinely sees 30-33,000 gross loads, it handles it like a dream but you have to question the the life span and legality of doing this. The cab and chassis has about 150,000 miles and my brother is extremely meticulous with maintenance, using Texas refinery oil exclusively,
Texas Refinery Corp The injectors just caused the first major repair since buying the truck new in 2004 Aside from that chewing a few starters and a minor electrical glitch at about 45,000 miles are the only issues the truck has had. He says the trans is operating at a higher temperature than it did new and currently questions its long term reliability from this point on. The Stellar Hooklift has been very reliable only needing a couple of cables that operate the hydraulics. The truck sees plow duty when ever it snows and the chassis needs repainting, nothing horrible, just preventative maintenance.
The International is a brute workhorse, not as fast at the Dmax but pretty much the same speed no matter what load is on it or behind it. He's had it for 5 years now, tires, fluids and filters are the only thing its needed with about 100,000 miles on the ticker. The IH is definitely a half million mile truck or more. It's so reliable, its boring to talk about it.
The hooklift will change the way you do everything, you can load a Bobcat into the can and tow another one on a trailer. Loading a huge stump is much easier with the dumpster at ground height. Loading by hand is easier because of this as well. You will like the hooklift, I'd recommend a 650/6500 series truck at the minimum to take advantage of the hooklift's capabilities, hope this rambling helps.:cool2:
