I wanted to share what I've learned over the past 20 years on grapple trucks. I'm not a pro builder or anything, I'm just a guy that grew up in the tree service industry driving different trucks and wanting a better setup. The short story is, I became an equipment operator in 2000 or so. Like many of you, I've got hours on bobcats,grapple trucks and cranes.
I worked with the family tree business until 2009, then I joined my older brother working around modified cars. Performance parts sales and build fast street/race cars. It was difficult going from a field operator to a desk job with a computer. I wore another series of hats but grew into the controller . We currently employ 40 people and the business grew significantly over the years.
We focus on educating the customer and getting them the correct parts for their builds. We strive to be the best in our industry for tech videos, knowledge, customer service and going the extra mile. With that being said, thats what I look for whenever I want something new.
My father and younger brother had a few trucks built over the years. As we all know, its difficult to operate a business and get everything perfect. Each truck had its strengths and weaknesses . Let's start with the 4 trucks over the past few decades.
My parents started their business in 1982. Purchased a well used 1981 L8000 in the early 90's with a log loader. Leaked fluids,lacked power and didn't stop very well. 25 yard bed.

2004- Purchased a 330hp C7 sterling 9501. My father always liked to wheel and deal. He purchased a large chassis, drove it to ox bodies in Alabama and talked them into building a 22ft bed for 12-14K or so. They had to push a few tables together to weld it all . Pretty sure they lost some money on that one! 50-55yds

The truck was driven to Tampa and Hydraulic machinery installed a Prentice 2124 with load holding valves . I never tested the hydraulic pressure but I'm sure it was set to 4000psi! The truck would lift 8500lb into the side door, or 6500lbs over the side! It would lift almost anything you can grab. Loader was nice but the truck was way under powered. 260-270" wheelbase.
Sidenote, my father always put a smiley face on trucks. The Sterling had a smiley face sticker on the back of the loader.
2013- My father looks into a 2013 Western Star 4900SF Glider kit with a Reman 500hp Detroit diesel series 60. The glider kit program uses a new chassis with an old pre emissions engine and trans. You can get a reman engine,trans and rear ends. An older engine will go over a million miles and not break down as much as some of the newer engines. The performance is much different compared to newer trucks IMO.
He decides to build a dual purpose truck with a 50 yd dump body for hauling large amounts of mulch. Great idea, but the wheelbase got a little too long (310") . It was difficult to turn and once a year would break some bolts that held the rear differentials to the chassis. The trans was also used and pretty worn out. Now,The engine has broken down once to date when the turbo gave up. Extremely Reliable.
That truck was driven to hubler to install the Prentice 2124 loader, then back to Florida to have the body put on. A few issues with different people having their hands in the project.. Lessons learned. Its nice to deal with a single person that installs the loader and body.

2015- They pick up a Western Star 4700SF with a 450hp DD13 and a 288" wheelbase. It turns much better but the body is still only 50yds. Prentice 2124 with Rotobec 046 trash grapple. My brother's recycling business is doing well so he purchased a few 110 yard dump trailers. He really needed a rear mount loader again.

A rear mount loader is superior to a mid mount IMO. You can build a larger bed and don't need to complicate things with a dumping hoist. A hoist also adds weight. You can also get the truck in tighter places and work off the back,or load trailers. Wider angle for loading material then a mid mount. Also less Diesel fumes IMO.
Most dump bodies are 40-50 yards and most rear mounts are 50-80 yards. Dump bodies have their place but as long as these trucks are you risk turning them over on unlevel ground while dumping or with weight in the nose of the body. It does take longer to unload small debris out of a rear mount but a skilled operator takes 5-20min at the dump.
2020- The Glider kit program is coming to end. Covid also hits . After the issues my brother had with his trucks over the years I push him into considering one last build. The two of us ironing out the kinks and getting it dialed in. He gives me the go ahead in June of 2020.
After building a few fast cars over the years and fine tuning other peoples builds I knew the importance of the right recipe. I spent hours doing research online and calling around talking to people. Not only grapple trucks, but all types of trucks. I wanted to really wrap my head around the entire process of building a truck. I spent about a month doing research.
July 2020. Once I was ready to place an order I quickly found I was too late to order a glider. Being the last year everyone was sold out of their allowed glider spots. I spent days calling around looking for a spot. Then I remembered Kustom truck in Oregon . Expensive but they've built some really nice trucks over the years. There is a T800 heavy haul that I may have looked at 100 times over the years.
Kustom Truck
We engineer and develop engine harnesses and parts kits for Peterbilt, Kenworth, Freightliner and Western Star trucks for engine swaps.
For a Glider, you need a chassis and a Glider spot so that its legal.
I contacted Kustom and spoke with Harold Bettencourt. He has a few spots left! He puts me in touch with Wayne Burroughs of Burroughs diesel in Laurel, Mississippi for a chassis. I explain to Wayne what I'm after and we work thru a few rough drafts of the truck. Western star has a body builder page where you can view almost every detail on the truck. Radiator size, suspension, frame size etc.

I also discovered a website that allows you to adjust wheelbase, add bodies and cranes. Its extremely helpful . I spend hours on it dialing the truck wheelbase and bed size in. I emailed them to ask them to add the Palfinger M13 Loader. Very helpful group of people.
Truck Weight Distribution | TruckScience
TruckScience - Truck weight distribution. Calculate axle weights, dimensions, centre of gravity and maximum payload to deliver safe, legal and efficient trucks
I want to take a minute to talk about CT. Cab to trunnion/tandems measurement. Its important to consider this instead of wheelbase for a few reasons. Weight placement,tail length and ride quality.
Wheelbase is center of front axle to center of trunnion/tandems. Some trucks have a longer cab or axle placement and that will effect wheelbase.
An example.
2013 Western star 4900SF with a 210"CT is a 300" wheelbase

2020 Western star 4900SB with a 210"CT is a 283" wheelbase

By choosing a Set back axle the truck gets a 17" shorter foot print. A little more front end weight also. Most people agree that over 283-290" WB it becomes really hard to turn these trucks . I can tell you that 310"WB sucked for around town. Too short on the wheelbase can also cause instability with too much tail weight or the truck can bounce.
Wayne sends over a proposal on July 22nd. I chose everything on the truck except the fuel tanks. My brother wanted large 23" diameter 120 gallon capacity incase we did storm work.
Chassis specs-
4900SB with the old school square hood . Throw back to the older trucks with old engines. We went overkill on the frame but will have the truck forever. 3/8x3 7/8 x 11-5/8 (3/8 outer with a 3/8 inner) I've seen some people use a thinner frame on these trucks (5/16 outer and a 1/4 inner) But most people use the 3/8 by 3/8.
20K front taper leaf axle. Supposed to ride easier then flat leaf. Although alot of Michigan trucks go to a 23K flat leaf since they haul massive amounts of weight.
Dual power steering and coolers
46K rears with a 4.10 final drive. 54" spacing 210"CT 284" wheelbase, long frame . Total truck length is 39'
Neway 52K air suspension (Its an upgrade over airliner and will handle off road better, its also lighter)
22918B heavy duty 18 speed with air to oil coolers. Water to oil coolers warm the oil quicker but eventually leak and can cause hefty repairs.
Eaton easy pedal clutch rated to 2050ft lb
Horton 2 speed fan clutch. Its electro magnet at low speed and has constant cooling that doesn't rob any power. Spring engagement for high speed. Less fan cycling and AC system will work better. May not be ideal for under 30* weather. Could lead to overcooling.
11 blade Kyser fan. We can always go to less fan blade if needed
1350sq in Radiator . Could've gone larger but with Florida being flat and a 2 speed fan I didn't think we needed it. More cooling will always take longer to warm up.
Fully polished alum wheels,full gauge package, battery cutoff,black interior,backup alarm
Battery mounted in cab. I wanted to keep it and the aftermarket relays (loader fan,fuel cooler fan ) out of the elements and save frame space.
Heavy duty AC compressor. Its Florida! Bed Attic will also keep the cab cooler . Another rear mount pro.
