Here are a few shots from the back of my year 2000 CSRE. No idea how it compares to a TC2000 frame.. but at least it's something to talk about.
Somewhere along the way a previous owner set it up with some extra C channel and a 2" receiver tube in the rear bumper for towing. The photo also shows the section of C channel spanning between the two engine sub-frame rails to support the front engine mount. (it's still called the front mount, I guess, since it's on the side where the serpentine belt is -- even though that's more to the rear of the vehicle)
The trouble is, the hole for the hitch pin is so far back that I can't find any ball mount with a throat long enough to reach. I began cutting out the receiver tube, intending to weld in a new piece with its hitch pin outside the surface of the bumper, then noticed there's another hitch pin hole drilled through it but hidden inside the bumper assembly. I haven't decided whether to use that inner hole with some kind of long-reach hitch pin like what B&W have done with their turn-over ball gooseneck hitch (click the FAQ tab and scroll down a bit for photos)
, or finish replacing the tube, or abandon the whole thing in favor of a new hitch like the Draw-Tite 41990
. My hang-up with the Draw-Tite is that the receiver would be lower to the ground than I like. But those angle brackets on the existing bumper setup aren't super confidence-inspiring: the misalignment is so bad that several bolts can't be fully tightened so that the metal is clamped together well.
Anyway.. that's where things are at with my towing with a rear engine.
