We've had it our several times this spring and summer and haven't had any of the problems that you've mentioned but will keep an eye out for them. We did have a problem with the electrics. We bought it with everything power - stablizers, awning, tongue jack. By the time we put the stablizers down, the slide and the awning out, there wasn't enough power in the battery to bring them back in. And they didn't seem to be connected to shore power nor did the battery seem to recharging from shore power. Took it back to the dealer who replaced a circuit breaker that wasn't resetting. Seems to be somewhat better now.
We tow it with a 2013 F150, 6.2 litre V8 with 11,300lb towing capacity and it seems to follow along quite nicely.
