Its compact 18-inch width and 33-inch height fit standard RV cabinetry. Always verify your specific RV's power and water connections before installation.
Do all these models include heated drying?
Most do, but not all. The SPT models and the COMFEE' CDF18A2BWW feature heated drying as a standard attribute. The Honeywell HDS18W and HDS18SS lists do not mention heated drying in their attributes. If drying performance is critical, check the specific features list for the model you choose.

It also helps maintain hygiene and can contribute to better drying performance when combined with heated drying.
