An RV slide creeps out after closing when its drive system cannot hold the room securely in the retracted position. Hydraulic slides commonly lose pressure through a leaking valve or cylinder seal, while electric slides may move because of a weak motor brake, worn gears, loose cables, or incomplete retraction. In this guide, I will […]

Your fifth wheel usually tows nose-high because the hitching point sits too high. A tall truck bed, raised hitch, low pin box, suspension modifications, or insufficient trailer height can create this mismatch. I will help you identify the exact cause and correct it safely. We will also cover measurements, bed clearance, axle loading, and suspension

A trailer pulls to one side when braking because its wheels produce uneven braking force. Common causes include weak brake magnets, damaged wiring, uneven brake adjustment, contaminated brake shoes, sticking hydraulic components, tire problems, worn bearings, or axle misalignment. In this guide, I will help you identify the likely cause. We will also cover safe

If your RV outlets work on shore power but not on a generator, check the generator-mounted breaker, generator output, power cord, surge protector, and automatic transfer switch. Because shore power works normally, the problem is usually somewhere along the generator’s separate power path. I’ll help you follow that path from the generator to your RV

Your RV outlets work on shore power because they need 120-volt AC electricity. Your house battery supplies 12-volt DC electricity, so the outlets need an inverter before they can use battery power. This guide explains how your RV power systems connect. I’ll also help you identify inverter problems, battery issues, tripped protection devices, and normal

One side of a 50-amp RV usually stops working because one of its two 120-volt hot legs has lost power. The failure may come from the campground pedestal, shore power cord, RV inlet, surge protector, transfer switch, main breaker, or breaker panel. I’ll help you identify which leg is missing, narrow down the failure, and

Yes, rain can cause an RV breaker to trip when moisture reaches an outlet, shore power connection, appliance, or damaged wire. The water may create a ground fault, short circuit, electrical leakage, or arcing connection. In this guide, I’ll help you identify what tripped, locate the wet component, restore power safely, and prevent the problem

Your RV battery disconnect may not shut off all power because some circuits bypass the switch. Shore power, solar equipment, chassis batteries, safety devices, inverters, and direct-wired accessories can remain active even when the switch is off. This guide will help you identify the remaining power source, test the disconnect safely, and decide whether the

A tankless RV water heater is better for continuous hot water and frequent showers. A traditional RV water heater is usually better for lower costs, dependable low-flow performance, and simpler repairs. Your best choice depends on water pressure, camping habits, climate, available utilities, and installation compatibility. In this guide, I will compare performance, costs, maintenance,

An RV roof coating is usually the better choice when the existing roof is dry, firmly attached, and structurally sound. A full roof replacement is necessary when you find rotten decking, widespread soft spots, trapped moisture, severe membrane failure, or damaged roof framing. This guide will help you inspect the damage, compare both options, understand
