jnphobe, we just had same thing happen to our '06 3400RL as we were preparing to leave campground in Rapid City, SD. The bolt in the cross shaft was fine. Had it looked at by repairman in Cheyenne, WY and he couldn't get the parts we needed so we made it Colorado Springs, CO and went to Camping World. Parts are on order and we are letting them do the installation. DH also finally gets the airbags for his truck!!
CW has been very good to work with. HL rep was there when we pulled in so had some good conversations about our continued breakdown problems. CW was able to call HL and get all the part numbers for our rig without having to teardown everything and leave us homeless with two cats, as we are full-timers. Gear box and drive motor are being replaced as well as cleaning/packing landing gear.
Meanwhile, we have decided to stay at the Fountain, CO KOA for a month and maybe longer to enjoy this beautiful country and cooler temps. Another BH and a Landmark are here but haven't met owners yet.
