I'm starting this thread to use as a reference for my self and others to get some ideas on how to properly and effectively modify our older/inadequate tow vehicles to enable better towing and less driver fatigue.

I have a '95 F250 4x4 SCLB with the International T444E V8 diesel engine and E4OD automatic transmissionthat I have had to modify significantly to be able to tow the ZT33BH comfortably and safely. I have done the following and I'll be sure to add pictures later;

PSD 6637 air intake modification, deletes poorly manufactured and designed airbox.

3" tubular downpipe, deletes EGT inducing, mileage robbing"crushed" downpipe found on all OBS PSD trucks. Can hear that turbo whistle now!!!

3.5" Cat test pipe, removes sootclogged converter, restored MPG and power.

Muffler delete, allows capacity for additional HP/TQ but makes the truck a bit louder.

EBC greenstuff brakepads and shoes, better stopping power!

TS six position tuner with stock/high idle/50/70/100/140HP settings, more manageable power, better transmission shift patterns and lockup timing.

Tru-cool MAX 40k GVWR Trans cooler with and additional 9 row stacked plate cooler from a 2001 PSD, no more E4OD high temps!!!! I'm logging 185* MAX temps after installation. Was 275+ before. triple disk torque converter, improved converter lockup and no slipping, ever. Saves transmission from input shaft breakage and high temps during unlockled times. CHEAP!!! $225!!!

Front add-a-leaf and air spring kit, these trucks have a tendancy to sag in the front due to inadaquate spring rate and a heavy engine. These modifications have reduced bouncing associated with the D50 TTB front axle (hinged pile of crap). Also assists in weight distribution as ride height can be altered with air pressure.

Rear 3000LB Air springs, best modification for the heavy tongue weight of the ZT33BH (1000+ lbs). I had to fabricate this completely as the kits were all of small, light duty quality due to space constraints. Mine are mounted inboard of the frame rails and are filled using a schrader valve near the license plate. 50PSI is more than enough pressure to level the heaviest loads.

Polyeurethane bushings in leaf springs, axle hinge points and body mounts. Cure alignment problems, wandering, funny cab movements and bed/cab alignment issues.

3 gauge package, EGT, trans temp and boost pressure. EGT monitoring is crucial as temps over 1250* can damage the engine. Trans temp is equally as crucial as running transmissions at 250+ degrees damages not only the fluid, but the clutch material. Lastly, boost pressure can give you an idea on what kind of fuel economy you are getting. The closer you are to "0" the more MPG you'll get.

Very interested on seeing what you guys have for older TVs!!!!
1995 F250 SCLB 4x4 7.3L PSD. E4OD, triple disk converter, TS 6-position tuner, 3.55 gears, 3" downpipe, cat test piped, gauges, tru-cool MAX.

2004 Ram 2500 with Hemi. Pulls our 33 foot 5th wheel (7900lbs dry and 10,000lbs loaded) like a champ. No mods. currently has 95,000 miles. 3rd set of tires (I don't take chances on thinning tread), All maintenance done by the book and on schedule. Still has original battery (stays in garage in winter which has helped prolong the battery life). I keep thinking I should replace it but it always checks fine. Replaced serpentine belt at about 70,000 miles (don't remember exactly but it is in my "log book"). It does suck the gas going up mountains.

2002 CC Duramax, Allison Trans. 417,000 isn KM and still going. It's had nearly every body panel replaced at least once but the motor and trans keep going. Turning it over to as a work truck for my guys was the biggest mistake of my life. My 08 Dramax got lemond by GM and I've never managed to get back into a diesel since.

1991 Ford ranger only towed a pop-up. Not exactly a tow vehicle but it was a 4.0 v6 with 217000 miles. Gave it to my son in 2003 took him about 9 months to kill it. Sad, it was pristine when he got it.

08 F-250 PSD CC 4x4. Only mods are Firestone Ride-Rite bags with on board compressor. Otherwise, it is stock and pulls great. I didn't like pulling my heavier Blue Ridge fiver with it at all without the bags, it made the steering too light and didn't feel safe at highway speed.

After replacing head studs, EGR delete, turbo, alternater,ect.,ect.,ect.,ect --- its still a pretty crappy truck. However it does tow nicely. Would love to buy a Cummings someday!

My brother inlaw has the same puller you have and loves it. He pulls a 30' TT.
I have the 2008 F250 V10 and works well for me.
