Is this forum really that negative? I don't see it. Maybe on a couple of threads, but that is it, and that is usually from newbies to the site and/or people who don't know/own the boat and expect it to be like all of the others they have owned. The engine hatch question is a fair one to ask. This forum makes the Ranger's more valuable, not less. It is boat manufacturers that hide their problems and keep their owners away from each other that is the problem. If the dealer mentioned really stopped referring prospective buyers to this site then they are being foolish and/or are not explaining the benefits properly to potential customers of having a site like this.
I have an R25. It is hull number 7 and many improvements have been made to this model over the years. I can say, without a doubt, that it is the best boat I have ever owned, even without those improvements. I put the boat in the water last week and everything just worked. After I cleaned, polished, and waxed it, it still looks new! I was just commenting to my wife the other day what a difference this boat was to our prior boat (at just 3 years old). That old, new boat was already falling apart.
Of course you have to take care of any boat. Just like you have to take care of your house, car, health, etc. If you are not going to buy a Ranger because you don't like how a hatch opens or because you might have to maintain the engine then boating is not for you. You are ignoring the big picture related to design, quality, customer service and community that Ranger has and, frankly, I think it would be better, in that case, if you bought another manufacturer's boat that didn't care about those things.
Here is are a few pictures from last week:
