While I dearly loved my 1984 Jeep Grand Wagoneer with AMC 360 cubic inch V8/4BBL carburetor, select-trac 4-wheel drive, and torqueflyte 727 transmission. It towed my 6,000 pound Overlander wonderfully -- but was at its maximum tow weight with the 4.11 differentials. One of the biggest reasons that I sold the vehicle was its abysmal fuel economy -- towing the Overlander was 6 to 9 MPG -- solo was never better than 10 MPG. With the meager 18 gallons that its fuel tank held it seemed like it was a near constant search for a fuel station. The plusses that I noted with my Grand Wagoneer included:
- Absolutely trouble-free four-wheel drive system.
- Memorable styling that you either liked (I did) or you dismissed the vehicle as a throw-back to the 1960s.
- The cabin was open and airy - - much moreso than my '99 GMC Suburban (the Wagoneer's replacement).
- The TorqueFlyte transmission was a transmission that inspired my confidence - - after proper band adjustment, it did its job with no complaints.
- Its air conditioner was absolutely magnificent as was its heater - - both did their jobs with minimal intervention.
- The four-wheel drive was so dependable, that I foolishly thought I could expect similar durability from GM -- was I ever in for a disappointment!
The shortcomings that I noted with my Grand Wagoneer included:
- Abysmal fuel economy. It is the only vehicle that I have ever owned in which I ran out of fuel repeatedly due to its extremely abbreviated driving range on a tank of fuel.
- Despite factory Ziebart Rust Proofing, I was having rather significant rust in both rear quarter panels at 10 years of age.
- Power door locks functioned erratically and three different dealers couldn't locate the root of the problem.
- Motor that operated the rear tailgate window seemed unusually prone to failure.
Good luck with your investigation!
