  1. Structure, Service brakes, Jun 7, 2024

    This is an updated report with additional detail. Sorry for any confusion this may have caused. * Baggage door routinely open while travelling. A number of items may have been sucked out of the RV while moving down the road. We try to be hypervigilant and pull over as soon as we notice the door flapping open, and we secure loose items in drawers. * RV doors routinely open. The front door always opens, even though we use the 'deadbolt'. It's usually held in place by a hand rail that folds over the door, but this occassionally comes open, as well. This damages the door, and we're concerned that the metal stairs could fold out. The rear door has recently started openning on travel days. It's hard to tell when this happens, but we have had to pick things up off the ground after making a left turn at low speeds. * Brake eletrical issue. We had the RV in for repair at the manufacturer's service center. They reported that some of the brakes weren't receiving the proper voltage and were thus non-functional. * Front bedroom Schwintek slide mechanism came loose. Slide was partially inoperable, and would start to extend out of the unit during travel. When noticed, depending on how far out it had started to come, we would have to go back into the unit and pull it back in to complete travel day. This was repaired by the manufacturer. * Broken welds on frame. The manufacturer service center replaced the rear steps. They did not identify the broken welds that were causing the floor (immediately above the steps) to sag, and thus allow water intrusion. This lead to the rotting of the floor of the RV. The manufacturer provided an estimate of ~$20k to repair the floor, but didn't include repairing the broken welds. * RV is unlevel / lists to the passenger side. The RV has a lot of heavy items on one side, and nothing heavy on the other side to counter balance it: shower, refrigerator, oven, microwave, and side deck/patio. The tops of the tires are clearly visible when looking a

  2. Service brakes, Aug 6, 2022

    Bolts holding brake caliper assembly to the axle apparently loosen and fell out while on the highway. This caused the caliper to drop, resting on inner part of the tire rim, leaving approximately half to one quarter of the caliper on the disc. Caliper caused significant gouging on the rim. During braking, the caliper was prevented from spinning during brake application due to it hitting the axle u-bolt retention plate on top of the leaf spring. In the very limited backing, the hydraulic line held back the caliper. Safety issues are the complete lose of the hydraulic system, causing the complete lose of trailer brakes. The caliper gouging the tire rim could have caused the rim to break, with the result of the tire departing the trailer on the highway and hitting another vehicle. Issue was found when I noticed metal flakes (tire rim) in my driveway where I backed my trailer to park it. Following the flakes, I discovered the issue. Grand Design, and axle/brake manufacturer Dexter notified via email. No response as of yet. Hydraulic brakes were factory installed at the time of manufacture.
