Hi hi! I'm here because I read some great reviews of things here and because I am cheap. I am driving a new 2009 Ford F150 4X4 pulling a Keystone Passport trailer which is officially 30 ft long. (My husband measured it and swears it is actually 28 ft long, but whatever.) We bought the rig and truck because we are retiring soon and we want to be able to escape the Canadian winter. If all goes well for us we may even become full time RVers. We are both scientists by training. He?s a physical chemical guy and I?m a biologist. I do all the driving.
Travel trailers are measured from tongue to bumper, so I'd be surprised if the body was actually even 28 feet, maybe more likely to be 26.
I have some travel trailer experience and would like to point out some safety concerns (not necessarily problems, but concerns to investigate) with your rig.
Please be sure that your trailer's GVWR, which I looked up and is 7200 pounds, does not exceed your truck's towing capacity and that the combined rig loaded, gassed up, and with both of you in it does not exceed your F150's GCWR. For optimal safety you should have a significant margin. I looked up the F150 and depending on how it's equipped you could be overweight or ok.
The trailer ships from the factory weighing 5140 pounds. That could easily be 5500 by the time you take ownership, maybe more. After you load your stuff in it and have some water in the waste and fresh tanks, you could easily be right up to or over its 7200 pound GVWR.
Be sure that you're using a good quality Weight-Distributing Hitch, that it's adjusted well, and that you're using it properly.
As for saving gas with that rig, there may not be a lot you can do. You probably already need to air up all the tires to their maximum for the weight they'll be carrying all the time. You could get away with the specified minimums for occasional use but for full-time use you should have more.
