After a brief and cursory review of the trails in the 'Wells Guide', I'm considering the following trails...
# in book. | Trail Name | (D=Difficult, M=Moderate)
45. Calcite Mine (D):
46. Truckhaven (D)
48. The Slot (D)
50. Pumpkin Patch (M)
51. Cross Over Trail (M)
52. Oriflamme Canyon (M)
54. Pinyon Mntn. Rd. (D)
57. Mud Caves (D)
58. Mortero Wash (M)
59. Los Pinos Lookout (M)
60. Bronco Peak (D)
61. Sidewinder (D)
63. Table Mountain (M)
64. Smugglers Cave/Elliot Mine (D)

For those who've been there, any suggestions on trails to do?

From what I've been reading, it seems the Moderate trails should be fine for a Montero on 31 or 32's & Difficult trails with 33's and some armor. Justice you've been on some of these trails before with both a Gen I and Gen II so any insight on the difficulty is appreciated.

If there are enough going we can split to 2 groups especially for those who don't want to do Pinyon Mtn. (which will be a trail I definitely want to do) due to its difficulty and of course the SQUEEZE obstacle where wide rigs like full size pickups will experience damage to the body.
