'07Blacktruck,
Well, again, Ford in it's infinite wisdom, was lacking when it came to flat towing in the Ford Ranger division. The two wheel drives, stick versions, may or may not be towable, you'd have to really talk to either Ford Transmission tech or, a good transmission shop to see what they say. You see, there are some stick trannies that are not as well lubricated in main bearings, shafts etc. when the input shaft from the engine, IS NOT TURNING. Just because the rear output shaft is, doesn't mean all the correct shafts etc. in the inside are which means, it might not be properly lubing itself. I'm not knowledgeable enough to give you qualified info on that subject.
But, as far as the Ford Ranger 4x4 is concerned, yep, Ford screwed up again. However, there are what's called "NTK" or, Neutral Tow Kits" available. They were discontinued for a while but, I think they are available again. As I understand it, it's really a nothing more than a plastic bracket that is mounted to the dash, that houses an LED with writing on the bracket that states, "OK to tow" or, something to that effect.
But, the second part of that NTK is, Ford (local dealership) has to re-flash the ECM to tell the transfer case to go into NEUTRAL. When that's accomplished, it will send a signal to that new little LED that's been mounted on the dash. And, as I understand it, that little LED and bracket, and the re-flashing of the ECM, will run you somewhere between $350 and $400. I've never had the pleasure of having to do it so, much of this is from memory from other threads on the subject.
The Chevy Colorado and the GMC Canyon don't need any NTK or, anything else. They're ready to flat tow, RIGHT OUT OF THE BOX.
I too, WILL NEVER MAKE ANY MODIFICATIONS TO ANY VEHICLE for intentions of flat towing it. I'm one of those that will look for one of hundreds that are flat towable, from the factory. That includes lube pumps and drive shaft disconnects etc. It especially includes ABSOLUTELY NEVER, NEVER, EVER, will get under a toad, to disconnect a driveshaft or, re-install it. I'll quit RVing if it comes to that.
Now, as far as your question on "Removing the key" when I'm done prepping the truck for towing. Well, following the short few steps it takes to get it ready, the last one is, removing the key. Well, that's kind of self explanatory. I mean, if you're INSTRUCTED to remove the key, it stands to reason that the steering will still remain FREE.
Now, again, this applies to not only my year but, I'm pretty sure also a 2012. But, if I'm not mistaken, the 2013 GMC trucks need the negative battery cable removed after all the correct prep is done. That sucks. There's ways around it but, it still sucks.
But, we're very, very happy with our '11 GMC Sierra 1500 4x4 Extended Cab. The bed is a 6.5' bed. The Rampage sticks out about a foot or so. No bid deal at all. Now, as far as the weight of the Rampage, well, to me it's not all that heavy, not at all. Heck, I'm 63 and can still lift one end of it, which is quite enough to load it and unload it from the truck.
Another buddy on here travels with a Rampage too and, he's got friends that either meet him and his wife at campgrounds or, they travel with him. And, if they're going to be at a campsite for a few days, he does like I do and, has that Rampage ready to remove in about 1-2 minutes and, he's got some portable, folding metal saw horses that he sets up right at the camp site. He and a buddy just slide it out and, on to the saw horses.
Now he's got his truck again, for his wife or himself to use as needed. That Rampage is steel. Yep, it's a bit heavy but, surely manageable with two normal sized gents. As far as the price is concerned, they're normally around $3,000.00 new. But, my ever diligent wife, was cruising Craigslist and found one, USED TWICE, for $1,750. Well, it was 315 miles from us at the time so, a phone call and a bit of negotiations and, we struck a deal for $1,500. It's the same as a brand new one. I've seen them many times on CL or ebay for good deals. You have to be ready to jump on one if the price and time is right for you.
When we were looking for a nice truck to tow, we had to expand our search perimeter to find what we wanted. Well, as it turned out, we had to travel out about 100 miles to get our nice truck. That ain't the first time for that sort of thing for us and, I'm sure it won't be the last. It was June of '13 when we picked up our '11 with only 21K on the clock. Couldn't pass that one up.
