I know this is a bit of an old thread, but a recent experience gave me some new information on this topic.
During the sale of our house, I ended up talking at length with a couple of guys that run a local appliance repair shop. I got to telling them about my plans to move the family onto a boat in the not-too-distant future.
They both agreed that when that time comes, avoid the Splendide and go with the LG combo unit. They said that they stock parts and service both, and they end up working on Splendide many times more often than the LG, even though there are both kinds of machines in the area.
Here is a link for them: Washer Dryer Combo - Portable Washer - All In One Washer Dryer Combination
It looks like they may be more expensive up front, but it also sounds like they may be less hassle in the long run.
Hope this helps.
