DH's ability to drive is not in question. He has successfully and repeatedly tackled far more difficult trails in Moab. You can google Steel Bender, Gold Rim Trail, Poison Spider, Hell's Revenge. In question would be the quality of the jeep. Farabee's site states they rent Rubicons--even so, we need to check out whether they are further modified. I saw a picture of what appeared to be a Farabee Jeep on some obstacles in Moab and we've seen them out on the trails when we've gone. Don't know if the Sedona ones are less modified than the Moab ones.
We also need to check out the repair clause. DH is used to doing his own trail repairs--and often repairs the breakdowns of others in our group or total strangers for that matter. However, we won't be traveling with his tool box, so that will be a factor.
DH shares the attitude with his fellow jeepers that "real jeeps are built, not bought" and has so highly modified his '84 CJ that about the only thing original on it is the VIN. Circumstances made him have to forgo his annual pilgrimage to Moab and he complains about it. The fun for him is in the challenge of the obstacles. He may agree to sit in on a tour but it would be like listening to the band when what you really want to do is conduct the symphony.
Thanks, everyone for your input. As I mentioned, DH is more than capable of driving (maybe we could retire to Sedona and he could conduct Pink Jeep tours

). The limiting factor is if we will be able to rent adequate equipment. Think I'll be contacting Dan Mick today for his views on Farabee or other places in the area.
