RVs and RV life is already fraught with a continual stream of repairs. Most full-timers are in reality part-timers because they spend much of their travels with their beloved home on wheels in a shop. From roof leaks to little tweaks, there’s always a lot to be repaired. So, don’t put your already repair-ridden RV living in a state of jeopardy by having a substandard holding tank! The last thing you want, when you’re traveling down the road, is to have a complication with your black water system.

The 42-gallon holding tank from RecPro is the way to go when it comes to adding a solid performer to your recreational vehicle. This tank is manufactured by the specialists at EPI (Elkhart Plastics Inc.) EPI is one of the TOP tank manufacturers in the entire world. Their strict processes, safety, and quality standards make their tanks especially strong when put up against the rigors of the road. The roto-molding process also ensures that the walls of your tank will be extra strong as it removes the majority of the impurities found in other tanks that are poured or blow-molded from other manufacturers.

Don’t let something as simple as a holding tank put your travel dreams on hold. Buy an EPI tank from RecPro and have peace of mind when you’re traveling down the road, or that, at least, this is one less item you’ll need to have your RV in the shop to repair!
