The Ekko seemed like a sufficiently good improvement over our 20 year old Roadtrek 200V that we bought one. The numerous problems reported in the Facebook group had us on edge. However, our unit is relatively trouble free. My impression is the original design goofs were compounded by Covid-related assembly crew problems leading to some remarkably shoddy early units. I suspect quality is now on par with the rest of the industry. (A low bar, I know!) Some dealers, like the one we are using locally, seem clueless about issues and unable or unwilling to aggressively get approval from Winnebago for warranty work.
The delivery time for ordering an Ekko is something like a year now. However, used units are turning up as people's lives change. Canceled delivered units crop up, which is how we got ours.
The ride quality on the original suspension is very smooth on good roads, but resembles our RT's drunken whale handling on its original suspension when the road starts to undulate. Like on our RT, we have upgraded the shocks and now the Ekko handles very well. We also lifted it for additional ground clearance.
The toilet cassette is great! You can empty it anyplace there is a toilet of any kind. If you go someplace without any sanitation facilities at all, you can carry a second cassette. To connect it to your sewer hose for civilized use at dump stations look up the "Americanizer." On our recent trip in the San Juan Islands our endurance was set by the 50-gallon gray tank. By using campground showers or taking frugal sponge baths we never completely filled it. We were able to stay four nights on San Juan Island, which no longer has an RV dump station. In the RT the black tank would have limited us to two nights.
The gear garage is largest we saw when looking at RVs of this size. Its three doors make it relatively painless to load our two bikes.
An important feature for us is the four-season capability. Skiing out of the RT with very limited fresh water and no showers was rugged.
The floorplan is working out well for us. We find it more livable than the RT. A big help is devoting part of the outside storage compartment to our cats' litter box whereas it was underfoot in the RT.
We got the optional second lithium battery without a generator. No generator maintenance is a huge win as far as I am concerned. With so much electricity available we use an induction cooktop rather than the gas cooktop, which eliminates the fumes and excess heat from gas cooking. For messy stuff like burgers we use the induction cooktop outside where it is impervious to wind.
Overall we are pleased with our Ekko. It needs some customization for our own purposes, and some people are really going over the top with alterations. But I think as delivered it is quite satisfactory.
