Hello from eastern KY! We are new to R-pod not to camping, travel or small RV's. I just bought a lightly used Model 177 and towed it back from WI this week.
I'll throw in some observations:
Tow vehicle is a 2015 Ford Crew Cab, F-150 Sport w/5.0 V-8. Our old T@B teardrop trailer weighs 1,574#'s dry and MPG is within one MPG towing the R-pod! Seems MPG is more about wind resistance than weight.
Side winds are, however, a bit more noticeable with the 177. I have a sway control ordered for less sway. It was never to the point of a being a safety issue, even during some very seriously bad weather en-route home but still a little bit noticeable, thus the small $35 cost to add sway bar is easily justifiable.
Only current other plans to modify,etc., the R-pod:
-moving the spare to the front & add a bicycle rack on rear
-repairing the end trim on the dining bench with different fasteners
-adding a Battery Tender pigtail for battery maintenance (I like using the better designed tender brands)
-buy another tire cover as originals missing-Whats best for money and service life?
-get adj. paint poles to install cover
-ideas from here...

I am a former skilled trades guy so hope to learn and use tips here from others!
