Question Apex 187RB and 191RBS frame the same?

Hello folks, I am buying an Apex Nano 187RB. I am aware the GVWR on the 187RB is 3800#, and the 191RBS has a GVWR of 4700#. I want to put a heavier rated axle on my 187RB, and need to know if the 187RB FRAME will take the additional load if I put on a 4700# or a 5200# axle and load it accordingly. IF the frames are the same, that would mean I can put on a beefier axle and have a higher load rating. An additional thought here is I will "flip" the axle, but that should not matter, I suppose.
Please someone, can you help? The nearest Apex Nano 191 RBS for comparison is 120 miles away.

Answering my own thread

I spoke to the very nice Forest River customer service person today. He said the frames of the Apex Nano 187RB, 189RBS, 191RBS all have the same frames, but where there is a slide the weight of the slide calls for a bigger capacity axle. This answers my question of can I put a bigger capacity axle on the 187RB and have the frame support the additional load. The answer is YES. He suggested a 4400# axle would be the next bigger one, but when I asked if a 4700# axle would be ok, he said yes. So folks, if anyone needs this information, here it is.

By the way, Dexter makes the 4400# axle, but TK makes the 4700#.
