TV concerns ???

Just came back from our first trip in our new Windjammer. Trip went really well, everything worked on the camper and good times had by all. The only concern was my tow vehicle. F250 Gasser w/ 5.4 and 373 gears. The TT towed great on flat land, however on grades the 5.4 was screaming ,slowed down some but still pulled the hill. I was told by the dealer that the 3065w Windjammer is 1/2 ton towable.( imagine that ) Empty weight is a tad over 7000 lbs. Am I expecting too much ? or is my f250 with 150,000 miles just getting tired. Another concern was visibility, even with the mirrors extended I was unable to see to the right side ( passenger side ) beyond the trailer, I just stayed in the right lane anyway, however I have a really bad blind spot to the right rear. I know most of these things are to be expected, however it starts to look like my trips need to be north and south rather than east to west across the mountains. Thanks in advance Chuck in Va

It's unfortunately the nature of the gasser beast, when climbing hills the engine is most efficient at its max horsepower point which is in the 5,000rpm range. It sounds awful, but I doubt there's anything wrong.

I have pulled from FL to Goshen in the Appalachians over to Missouri thru the Ozark Mtns, and back thru the Smokeys to Concord and never get over 3000 rpm with a 5.3L Silverado and a 3.23 rear end. Glenn Gurzcyk followed me to Goshen last year, so ask him how the gasser did. I don't even try to go 55-60 in the mountains because semi's sure don't.

I didn't get to 5000 rpm, usually got to around 4200 at the top of the hill. I am not interested in doing any land speed records, I am comfortable towing at 55 mph and sometimes a lot slower on curves. I am semi retired and NOT in any hurry. So I guess it sounds like its ( the 5.4 ) doing what is supposed to do, I am towing with the overdrive off. So when the DW states it sounds like the engine is coming apart, I'll just tell her "That's just power honey ", works for me. Thanks again. ( sure would like a diesel, but its not in the cards right now )

On level, mine turns 1800 @ 65 in 4th od. It sure won't hold it on any incline and immediately kicks out of od and jumps to 2400-2500 rpm. 55-60mph in 4th in tow mode, it turns around 2500-2800 which is where I tow 90% of the time. I have no complaints. See no reason to run 65-70. JMO.

SKnight, at 55mph I believe I am at 2200 rpm, no strain on the 5.4 on flat land. Just a concern on hills, haven't been on any mountains yet only foothills. The 373 gears are great for pulling a 5500lb boat off the boat ramp but lacks top end power. As long as it sounds like its doing what its supposed to do, then it makes me feel better. I have to remember at least to me I'm pulling a lot behind me. thanks again for the responses Chuck in Va

I just pulled our new Puma 31-RDKS (7952 on the sticker- I guesstimate I was running in the 8600-8700lb range) from Ohio to NE Texas with an F150 Ecoboost with 3.55 gears. Locked out 5th and 6th and was pulling in 4th, which is 1:1 like you have with OD off. Ran at ~2800 RPM at 65. Not in the mountains, but did encounter some pretty long grades through Kentucky and Tennessee and never even had the torque converter unlock. The longest, steepest grade I encountered resulted in a 3 mph loss(down to 62 from 65)- trucks were in the right lane with flashers on running 45ish by the top. I was pulling with a ProPride 3P which was a joy. I've had a 5.4L and still own a 4.6L. You'd be amazed at how much better the Ecoboost pulls- so, yes, your camper is easily half ton towable- with the right half ton, that is. If you don't have the money for a diesel, I highly recommend checking out the EB F150's. I know some dealers are running STEEP discounts. I'd venture you could get a nicely equipped 14 model 2x4 Crew for $27-$29K.

I have heard great things about the ecoboost f150, I wish I could take one for a towing test drive, I understand the power range is a lot different with the turbo. Lots of used one out there also.

I think your 5.4L is doing just fine. Remember, it makes its peak power in the 4K RPM range. It sounds like it's screaming (well...it is screaming), but it is natural for the 5.4L (and 6.8L). As long as you are keeping up the maintenance on the truck, you will be fine. As you mentioned, a diesel would cure a lot of your ills (well, wants anyway). If you are planning on lots of mountain trips later, you will surely want to get one. But for now, I think you are doing just fine.
