✓ TL;DR The Dometic 310 and 320 share the same basic gravity-flush platform, two-bolt mount, and several service parts, but they differ in bowl shape, rinse behavior, and size. Per Dometic’s published specifications, the 310 needs a 10-inch rough-in and is 19 inches deep overall. The 320 needs 11 inches and runs 22 inches deep … Read more
✓ TL;DR The Camco RhinoFLEX 20-foot kit is the best RV sewer hose for most owners. It has a steel-wire core, a clear elbow, and it fits inside a standard 4-inch bumper. Full-timers who dump weekly should step up to the Valterra Viper or the cam-lock Lippert Waste Master. Budget buyers can start with the … Read more
SEAFLO’s RV toilet lineup ranges from a $170 plastic model to a $310 to $380 elongated ceramic version, and SEAFLO says its toilets are factory-installed in RVs from Forest River, Jayco, and Winnebago. Rough-in specs vary by exact SKU, and in two cases a retailer’s own listing conflicts with its own support answers, so measure … Read more
✓ TL;DR For a floor-level small bathroom, the Dometic 410 is the safest porcelain pick at a 7.625 inch rough-in. On a raised platform, the Dometic 411 shares that rough-in with a lower seat. The Dometic 400 and 401 are among the lightest current choices in plastic, and the Thetford Aqua-Magic VI is a similarly … Read more
TL;DR: The Dometic 400 Essential is a lightweight plastic-bowl RV toilet built on Dometic’s newer 400-series platform. It uses the same short 7-5/8-inch rough-in as the porcelain Dometic 410, weighs about 9.5 lbs, and costs less than porcelain models. The main tradeoff is bowl care: plastic can stain and scratch more easily over time, so … Read more
TL;DR The Dometic 410 is one of Dometic’s newer porcelain RV toilets, built around a short 7.625-inch rough-in that fits many bathrooms where the older 310 or 320 won’t.

TL;DR An RV black tank not draining usually comes down to one of seven issues: a clog at the valve outlet, too little water in the tank, a poo pyramid, a blocked roof vent, a valve that is not opening fully, a frozen tank, or a bad sensor reading. Before you touch anything, make sure … Read more
An RV toilet that drains slowly when flushed usually points to one of a few things: not enough water in the tank, a partial clog, a blocked vent, or too much toilet paper sitting in the line.

TL;DR: An RV composting toilet fan not working is almost always a power problem, not a dead motor. Check the fuse, the connector, and the 12V voltage before you assume the worst. If the fan spins but it’s still not pulling air, the vent hose or insect screen is usually the real issue, not the … Read more
TL;DR: An RV composting toilet that’s too wet has several common causes: urine in the solids bin, over-watered coir at setup, a weak or failed fan, high ambient humidity, shower water in a wet bath, or rain entering through the exterior vent. For mild cases, add dry coir and confirm the fan is running. A … Read more
