My wife and I just purchased a P17QBH and I have done several things to it already. However, at the moment it is back to Camping World to have some things fixed under the 30 day purchase.
First off, the winegard 360+ doesn't work. I took the power switch/coaxial junction box down to inspect and lots of cut out debris in ceiling, made a huge mess on bed. One of the 12 volt power wire feeds was pinched between the roof material and joist, after about 30 minutes of struggle, I was finally able to free the wire. Every coaxial connection in the TT wasn't even finger tight. My winegard has either a direct short in it, or the cable running to it has a staple ran through it because it kills the power supply. If I unplug the cable, the power supply restores. So the dealer will have to remove the antenna as it is glued to the roof and no further troubleshooting can be done by me without breaking warranty.
Second, the bathroom faucet had a faucet that doesn't match the kitchen style, so the handle hits the toothbrush shelf when trying to use hot water, so I replaced it with the same style as the kitchen, but in chrome to match the bath sink. I suspect it is due to shortages and the replacement faucet wasn't really thought out too well.
Third, the stereo had no reception, which is what led me to find out that the winegard was shorted. But the coaxial connections to the stereo antenna wasn't even finger tight as well. Also, there is a cable going from the TV to the radio, and can be used either direction but only one choice at a time. You can use it to send tv audio to the radio which is what I did since the stupid radio usb doesn't play music, so I have to use the usb on the tv and send it to the radio. So dumb. Anyway, that radio is getting replaced just as soon as the camper gets back home. You can also send video and sound to the TV from the radio, but since the radio is junk, not much reason to do that. Maybe if you was playing movies on your cell phone connected to the radio BT and then sent to TV but I suspect the radio won't handle that either since it can't play usb music. My new double din car stereo plays usb and also plays dvds and such, so that will be nice to send to the tv. It also comes with a backup camera that I will install over/around the front door and wire it to be on when the radio is on.
The solar on the roof runs to the controller in the basement and tries to keep the battery charged. The inverter when on shore power, also keeps the battery charged while providing all the DC in the TT. The inverter is wired to power only two specific outlets. One single plug outlet next to the inverter in the basement, and on my model the one double plug outlet (basically a standard outlet) next to the inverter remote control unit on the side of the forward salon seating. When on shore power, the inverter passes the 120v AC to these outlets, and when no shore power and the inverter is turned on, it will work off the battery powering the two outlets with 120v AC although the 1200 watt inverter won't power any heavy appliances.
Speaking of this location, this seat hides some potential storage. I took the screws out of the top plywood and drilled and sanded a 1" finger hole in it to make it easy accessible. I tidied up the wires down below and now this area can be used as storage. I plan on adding a piece of paneling later to hide the backside of the AC and DC outlets to make it an official safe storage area. Side note... the corner trim pieces on the back walls need cut to allow the plywood to slide under and thus fit in between the front trim that is sticking up and the back walls. Otherwise, all the weight of any person sitting down will be on the thin trim pieces sticking up. This is bound to break in short order unless the plywood is seated properly.
The water pump area had a leak from loose connections and the pump was installed on the floor out in the middle of a huge area next to the water heater. It was installed in a way that was impossible to remove the prefilter to clean or inspect it. I installed a 1x4 on the backside of the salon seating and installed the water pump vertically on this. This allows me to easily view and service the prefilter, as well as have a large area of storage space freed up. I plan on installing a RO system in this area. This whole area and under the storage drawers were full of trash and debris and the wiring was a mess. So sad.
I removed the plywood seat on the other salon seat to gain access to all the incoming wiring and plumbing as well as the back side of the breaker panels. Loose connections again on plumbing and coaxial. Place was a mess, made rats nest look tidy. To busy for any storage, but I tidied it up anyway. I screwed this one back down as I wouldn't want inexperienced hands digging around in there.
That's about as far as I have gotten on it. Hopefully, we will get to use it pretty soon.
