When was the last time you free fell hooked to a friction rig or have ridden the ball? Groves are for sissies on rubber tires. Get high, get high, get high! Tap that hat!The pull behinds are fine to around 40-45 ft used them many times.
Extra support under the outriggers is a must in the dirt. (4x8's) work well. On concrete they are fine.
I rent them for like $150-200 for 24 hrs. About $300 for a weekend(Fri-Sun).
135ft...Geez Child's play!
Try a man basket at the end of a 75 Ton Grove Crane with a 208 ft Boom. Now that's FUN!
All the Best
