Recently bought a 2004 F-150 V8 4x2 SuperCrew with the 4.6L / 3.55
ratio. I’m really confused as to how big of a trailer that I can tow.
The owners manual says 6200# GVWR. I know what it stands for, but
what does the GVWR mean? Should I be looking at a different number?
Any help is greatly appreciated.

GVWR is vehical weight, GCWR is max combined weight, truck and
trailer. I would not go over about 4000lbs with current setup tops and
not a trailer with a lot of frontal area (like a tall camper) as you
just do not have much "beans" there to work with. If you have your
heart set on a camper, if you regear to about a 4.10 you should be
okay up to 5 to 6000 lbs with a bit more frontal area too. This is
real world rating, not factory sales hype or ratings as they can be
overly generous sometimes. Nothing worse than a
underpowered/undergeared tow vehical and if you happen to live in
montana as your name suggests your elevation is higher so capacity
will drop because of reduced engine power. You can make up for some of
this though with deeper gears. Many many years ago they used to ship
trucks to higher elevation dealers with deeper gears but they stopped
the practice shortly after emissions came into play.

Thanks for the info SnoMan. I probably should have gone with the 5.xL
engine, but I got an incredible deal on it.

Any rough estimate on the regearing cost? Thanks for your help.

The actual gears on line cost about 150 bucks or less, at a dealer
they would likely be 400 or so just for geasrs and about 800 to 1000
bucks for the job. Since it is new if dealer does it is would be
covered by warranty if that is a concern but changing them will not
void warranty on rest of truck even if done by a third party (actually
it will help if you tow with it because it will easy load on engine
and tranny and they will not be able to say it was not properly geared
for the load). If you farm it out you should be able to get it done
for around 250 to 300 plus gears because the Ford 8.8 is not a hard
rear end to work on and is sturdy for its size too. If it is done
correctly by someone, it will not have any problems for life of truck.
How big of a trailer are you looking at? Also if you had gotten a 5.0
you not have been much better off if it had same gears too. Use money
you save to modify it for your needs as gear changes are not a big
deal and a lot easier and cheaper than a new tranny and since it is a
2wd truck, it is simpler yet.

The trailers that I have been looking at are around 4200#-4600# dry
weight. From what your saying, I should regear it for that kind of
load. Good to know that the 5L would have left me in the same
situation - I’ve been debating whether to trade it in, but really
don’t want to give up this truck. Thanks for the good advise, I’ll
start shopping around for someone to regear it.

You will do fine at around 5000lbs with a regear to say a 4.10 and add
a aux tranny cooler too but you do not have to go overboard in size.
People that do not have the trucks properly geared and setup for loads
are the ones that have problems. In hot thinner air, the effiecency
of cooling system drops some so you want to add a little extra
insurance when towing for tranny with a aux cooler if it does not
already have one and the deeper gear will not only give you more
towing power but also ease tranny strain and heat some. First time you
drive the truck after a regear you will think someone put in a bigger
engine. Where about in MT are you (if you are) I lived in SW MT for a
while in the mid 90’s.

Actually I’m in a suburb of Los Angeles, West Covina. I just hope to
move to MT one day. Big Sky country, that’s for me. Wife says no
way, but I’ll get her convinced eventually. The websites that I’ve
visited, none of them list tranny coolers for my 2004. I see the
F250/350, is there something strange about the F150? Thanks for all
your help SnoMan. BTW, did you like MT?

Go to Advanced Auto and they have the generic kind I have used for
years that work fine. You what something about 5" x 12" or so. It
can be a little bigger but do not go overboard. MT was okay but it
depends where you go. It kinda went down hill when the legalized
casino gambling in the early 90’s and has doing so ever since. We wnat
to retire in Colorado in 5 years or so (west of the divide but kinda
along I 70 corridoor) or maybe Wyoming around Casper area. I like
Wyoming a lot because it has not really changed much in last 20 years
and your dollar goes further and has very low property taxes and no
income taxes (MT is very bad about both of those) and Wyoming will not
legalize gambling because they saw what it did to Montana. Parts of
Idaho are nice too. Aome about the size of what is in link below
would work fine for you.

Or maybe this one if it is hot a lot and you have some serious grades
to climb but it is a bit large though

People tend to get carried away with these and add more than they need
size wise.
