We love ours, took delivery last September, and camped every weekend after including the first weekend in November.
After my wife saw the floor plan, everything else we looked at got compared to the 8329.
I think the two opposing slides and lack of overhead cabinets extending from a wall, make it very open feeling in the kitchen and living area. The entertainment center is in a perfect spot, and we like the room in the bedroom too. If we ever go back to a 5th wheel we really like the 8289WS, but not sure we'd want to give up the room the bedroom slide gives for the extra outdoor storage.
No leaks so far (fingers crossed) on ours, and I think the quality for an Ultra-Light is generally very good. The only issues with ours has been some scraping on the bottom of two of the slides, and a small fabric split in one of the window valance arms. Our dealer adjusted the slides and replaced the valance arm in under two weeks and I also had them swap the blue lights in the Renaissance fridge for white one's.
Mods so far
Goodyear Marathon LRD tires
Battery charge connector - (Charge without hooking up shore power)
OC awning supports on main awning
4x - 5" fence posts for storage - (Next to the steps and between the slides)
120mm quiet fridge fans and improved air baffle
Swapped both thermostats for residential digital units
12V LCD voltage monitor panel
Deleted the factory water filter
Split the kitchen AC outlets on to a 2nd breaker
Dimmers for awning lights
Tongue storage box
Move the sub-woofer from under the sink (yes really) to entertainment area
Add 20amp input, and install 2nd island AC outlet for space heater when on 30A
Move low point drain valves inside (space dependent)
Whatever else I can think of
Just waiting for warmer weather now
