Its under-sink installation type and relatively small size (13.5 x 6.5 x 15 inches) make it convenient for tight spaces commonly found in RVs. Being lightweight adds to its portability, a handy feature when space and weight are critical.

Installation is user-friendly given the under-sink design, making setup manageable for most users. As a US-made product from a veteran-owned brand, it may appeal to buyers valuing domestic manufacturing.

This unit offers a space-efficient and lightweight option for RV water softening, providing a practical choice for those looking to improve water quality without sacrificing valuable space or adding significant weight.

The On The Go OTG4-DBLSOFT is a portable RV water softener designed for users looking for an efficient way to improve water quality while on the road. With a grain capacity of 16,000, it produces approximately 1,600 gallons of soft water and regenerates quickly using just two boxes of table salt in under 30 minutes. This feature makes it an excellent choice for RV owners who value performance and convenience. One standout strength is its compact design, which allows it to fit in tight spaces, enhancing portability and storage. The softener is also easy to install, requiring no tools or electricity, and connects seamlessly to standard garden hoses, which is a big plus for ease of use. The large opening for salt addition and the movable base for leveling on uneven ground further add to its user-friendly design.

However, there are some drawbacks to consider. While the softener can provide substantial soft water, its effectiveness can vary based on the hardness of your water source. If your water is particularly hard, you may find that the capacity can be somewhat limited. Maintenance is generally straightforward, but users will need to regularly manage salt levels and monitor the system to ensure optimal performance. The unit weighs 32 pounds, which may be somewhat heavy for some users to handle, especially during relocation or setup.

The On The Go OTG4-DBLSOFT is a solid choice for RV and marine users seeking an effective water softening solution, but it's important to assess your specific water conditions and personal handling preferences before making a decision.

The GoBluTech R3 Water Filtration Unit + Water Softener is a comprehensive solution designed for RV owners looking to enjoy clean and soft water on the go. With its manual operation, the unit does not rely on electricity, making it a great fit for mobile lifestyles. Its compact dimensions (16.65 x 6.5 x 8.5 inches) and under-sink installation type ensure that it won't take up too much space in your RV, which is always a plus when dealing with limited room. The heavy-duty construction promises durability, an important factor considering the wear and tear that can come with travel.

Additionally, at 38 pounds, it’s relatively portable, though some users might find it a bit heavy for frequent moving. The product's ease of installation is another highlight, allowing users to set it up without needing professional assistance. The manual regeneration process might require some effort and monitoring, which could be a drawback for users seeking a more hands-off approach. Those who prioritize low-maintenance solutions might find this aspect less appealing.

Nonetheless, the bundle is produced by a US veteran-owned company, which could be an additional point of interest for those wanting to support such businesses. The GoBluTech R3 offers a sturdy and space-efficient option for RV water softening, and potential buyers should consider its weight and manual regeneration process in their decision-making.
