About Black Tank Deals

Black Tank Deals is run by working RV solar installers. We built it for RV owners who want a real price and a useful explanation before spending money.

Fun headline. Straight answer.

We open the retailer's page, check the exact model and offer, and explain what it fits. Lithium batteries, solar and inverters get particular attention, alongside the unglamorous gear that keeps an RV comfortable.

We earn commissions on some purchases. A commission does not earn an Installer Approved seal, change the price you pay, or turn a weak discount into a deal.

Prices move. Every deal carries a check time, and ended offers move out of the live lists. Here is how we choose them.
