We have owned a few trailers including a pup, hybrids and one small TT. I have learned what works well is if my DW and I take 30 minutes to sit in each and visualize the experience.
The whole point is to ask yourself at the end - Can you live in it for a week or weekend? What if its a rainy weekend?
I personally like the Surveyor line and have only admired a few Rpods at trailer shows so take this for what its worth.
From looking at the two, I can tell you that the stools in the Rpod 181 wouldn't work for us. I like the couch for reading at night. Also, the bed is too short (I'm 6'3").
How light do you camp? The Rpod has 1,000lbs of CCC so be careful how you load. Cargo, mods, options, water, batteries and a WDH will quickly add up. How much you load is a factor of how you camp and is completely personal so what works for one may not for the other.
Good luck in your decision and
