TonyD, thanks for the great info. This is will be a first on many levels - ATV trip (I have experience from AFG, IRQ, and other armpits of the earth; wife is amateur); and highest level of elevation I have towed our 34' TT (have done switchbacks in Appalachian and Blue Ridge). We arrive Taylor Park (staying in their RV park and rest of party has a cabin) on Monday 27 June. Will you still be in the area?
Again, thanks for the GREAT tips - some were reminders for me. Cheers!
