Do you have a VENT that's available in the closet?
The combo units are around 32" tall and stackables probably around the same. Just take a look in the closet and see if you were to go straight up with the stackables, is there room? I've seen some of the older closets that ONLY a combo will fit. Newer units like yours may have room for stackables.
I would recommend a VENTED system and in stackables that's probably the only way the dryer will be available. But in the Spendide line of combo units, vented and NON-vented are available.
Don't know where Rocky Point is, so this may be of little use. I purchased a new 7100XC Spendide two years ago for our toy hauler and it had to be non-vented as the hookups were in the center of the garage front wall. We haven't had the opportunity to use it only twice and yes, it does take a long time to dry, but it does work well none the less. I'm going to be carrying a larger car now in the garage and we have no room for the washer/dryer combo unit. If you're interested, $1,000. List is around $1,500 and Amazon and Camping World are around $1,300. Just throwing that out there in case.
Good luck with your new toy hauler...
I have a few pictures if you're interested, let me know!
