Craig, I have a 2000 Tacoma TRD 2WD with a locking diff. It's quit a bit smaller than the 2006 and is a great vehicle. The 2006 is a better "mid size" than mine, but even so the 2000 tows very respectably. You hardly know you have a trailer (of resonable size of course) behind it. I've trailered my off hiway pop-up with it just this last weekend, back beyond sanity for most people. I can only imagine the 2006 would be even better. Maybe with some toutalage you wife would get used to towing, mine has. Starcraft makes a sweet off-road capable popup, check out the Startcraft 11 RT. It will pretty much go anywhere your truck will go. The 13 RT has a potty and shower which will please the wife.
