We've had our 27-5L for two years now and still happy with our decision. For the money I believe you will be hard pressed to find a better option especially when you look at and consider the frame it is sitting on. We had a few minor warranty things that got addressed hitch was no different than a new 2008 Komfort TT we purchased did. Our cabinets are fine and I've repaired a few stripped screws. Like Scott G, we were looking at Grand Design but there were many things that we felt weren't great they put in their rigs. We were very interested in Glacier Peak, went to look at a floor plan our local dealer didn't have , saw our 27-5L and didn't look back.. Glad we did.
I've done many mods including installing solar so have crawled around ours many times. Northwood does build a good rig and with many better componanants (like converters) better than others in the same price point.
If you are on Facebook look at their post done a few days about about the building of their aluminum frames
