No idea, sorry, but "welcome!"
Been waiting for others more experienced to chime in, and if you have been searching archives here there is a gold mine of advice by current and past teardroppers.
@mbirnbaum
What do you mean by "wings" exactly?
Something like the attached side and rear tables that are options on a 560?
I've got a couple camping tables from tent camping like you can get at REI I can set up but they are a bit rickety compared to the ones attached to the 560.
This one is on sale and the similarly braced but square one I carry in 560 if I want a place to set out food beyond the side tables works well enough.
If you are frugal and expect longer hard use over a couple three years I'd go bigger. Like what you might get at Home Depot or Lowes. The trick will be where to stow.
I'm sort of surprised we are not seeing more RT owners asking questions here. Lots of good advice on gear thats separate from the CI but useful for RT, and camping places that work for both.
I wonder if the RT folks have their own webforum or FB group. That would make sense as numbers increase and folks get on the road.
@Cary Winch how many RTs out the door so far?
