By Texas Canyon are you reffering to what is now called Rowher Flats? What trails have you done there? I would think that Rowher and Lookout trails would be too difficult for a 2wd IFS rig. I don't know your skills or willingness to push it, so I'll just list all the trails I know of near me.
There is Drinkwater Flats a few valleys over (betwen San Francisquito and Bouqeut Canyons) which has a few easy trails, but the main entrance is quite a climb even for a stock 4wd. And theres another trail or two between San Francisquito and Hughes Lake Rd.
There is Azusa Canyon OHV, but they likely won't let you in because you are 2wd.
In the Gorman/Mt Pinos area there are a few good trails in and around Hungry Valley OHV & Miller Jeep Trail.
And then out past Mojave there is Joshua Tree and some other OHV and Last Chance Canyon.
For any pics of these places check out my website link in my signature, especially between 2000-2002 when those locations were still difficult & fun. And if you need a buddy to wheel with I'm always up for a wheeling trip.
