Awhile back I had a thing for the Sierra Line. I thought they weere decent and well built. At the time they were having issues with front flexing on some of their models. I do believe they eventually resolved those issues. A couple of years later I came across the Open Range line. I was hooked totally.
I like the modern interiors of the Open Range vs. the country decors in most RV's. OR has show to be very innovative and offer lots of standard features.
Open Range models are typically 1000 pounds lighter then comparable models due to the cable driven system they use to move the slides in and out.
Some consumers are leery of cable slides. OR did have issues with the slides initially but at this point all the kinks have been work out and the problems have been resolved.
Most importantly they do stand behind they product. I have had no major issues with my unit. I did upgrade the OEM tires after having a blowout.
The OP mentioned wanting the additional bath room. I have a full and a 1/2 bath. The second bath is nice when we take friends and have a full house however for the most part a family of five can make do with just one bath. The second bath has its own grey and black tanks which means you have to dump 4 tanks. The additional tanks are just extra work.
In hindsight I would have no problem with one bath and eliminate the additional tanks. It's the added tanks and additional dumping that I don't like and not the bathroom per se.
The OR 389 was not available when I purchased although I do not like the outdoor kitchen I do like the larger single bath vs. 11/2 baths.
I consider second baths and outdoor kitchens features I could do without.
In the grand scheme of things,2 toilets,2 microwaves,4 sinks are really a bit much. I would prefer using the space to improve the layout vs. having duplicates of everything. An RV is only so big why have 2 of everything?
