Congrats on the new rig, welcome to the forum and good luck.
We have the Spledide units but ours are side by side as they could not stack in our Pinnacle floor plan. They work well and are reliable and we run them just about every day year round. Joan insists that they are the key to full time and without them we would be back to a stix and brix.
The only limitation with them is the heavy bedding items like comforters. We just got the Beddy system (https://tinyurl.com/y2k9e8a9
). The Beddy solves the problem of making a bed in the narrow confines of an RV, but the zip-apart top and bottom components are each too big for the splendide. They will physically fit, but they are often too heavy to allow the spin cycle to run**. So once a week we will have to cry uncle and go the RV Park machines.
**Fun fact I just learned last week: The Splendide has a logic routine that senses a potential out-of-balance condition before the spin cycle. It will attempt to re-balance the load by switching tumble directions a few times. If it fails to re-balance the load, it will simply finish the wash without the spin (followed by 5 hours in the dryer). This normally only happens when there are large towels or other heavy items.
