I run about 2600 to 3000 RPM in third. The kicker is I have to be above 55 miles a hour or my power range is horrible and maybe have to go down into second. My truck is 7000 GVWR and camper is 5500 dry.
Okay the question is here? First of all am I beating on my truck or just towing nice and heavy? Or is this normal with a 1500 truck.
Second is how do others drive in wind? Do you prefer to go easy on truck? Or its fine to push it hard. Any info to ease my mind that this is okay for my truck ?
All trailers are hard to tow in the wind. Fact of life. Unless you've got a monster tow rig.
Download and have a look at that.
Read the last paragraph on page 4-70. Your dry weight is already 500 lbs above the trailering package requirement. Note that is says REQUIRED
. That means you are not safe if you do not have the option package and pulling your particular trailer. Your vehicle is already outside it's designed limits if the option is not on your truck. Check the RPO codes in your glove box label to see if you have it.
You may have a problem waiting to happen since you're over the 5000 lb trailer package requirement weight already. I'm willing to bet your loaded trailer weight (food, clothes, water, stuff, etc) is at least 1000-1500 lbs over the 5000 lb limit.
Go here : GM-Trucks.com*|* RPO Code Lookup
:to decode the rpo codes. You can find out everything from rear axle ratio's to interior trim from the rpo codes.
Then look at all of page 4-71 to 4-81 and see where you sit.
After all that, go back and read 4-68 to 4-98 inclusive for the rest of the basic vehicle trailering knowledge you need.
for a frame of reference, my 98 k2500 with a 6.5 turbo diesel and 4:11 rear gears tows my 2011 Flagstaff classic super lite 831rlbss fairly well and that has a 6300 lbs dry weight/8400 lbs gvw. My truck is rated up to 10,000 lbs trailering with a WD hitch.
But I also keep it around 55 mph, and slower when crossing mountain passes. Any faster and it begins to struggle. It also will drive my egt's (and ECT's) into the danger zone if I sustain over 55 mph for a prolonged period of time.
You need to slow down.
You also may not have enough truck for your trailer depending on it's options. It's hard to say about your specific truck without knowing the options and ratings, but you sound pretty close to the max ratings for a K1500.
That means it's going to be working hard when towing and maxed out everywhere.
That means not only power. That means brakes, suspension, etc.......
