Gear We Recommend
Stuff worth buying and installing yourself -- picked for reliability and value, not just whatever ranks first. Where a job needs certified hands (sealed refrigerant, gas lines, inverter commissioning), we say so and point you to booking instead of a product link.
Disclosure: Some links on this page are Amazon Associates affiliate links -- if you buy through one, United Mobile RV earns a small commission at no extra cost to you. We only link gear we'd actually put on our own rig; this never changes which brands we specify or install professionally (see our certified install brands for that).
Power
🔋 Lithium (LiFePO4) Batteries
Any quality LiFePO4 with a real BMS is a straight upgrade over lead-acid for daily cycling and weight. For a DIY single-battery swap, a well-reviewed drop-in works fine -- for a full house-bank rebuild with real load calculations, that's a booking, not an Amazon order.
Full house-bank rebuild?
Multi-battery banks, BMS-to-Victron integration, and real load-calculated sizing -- Epoch is our go-to here, professionally specified and installed, not a parts swap.
Book a Service →Battery monitor
A shunt-based monitor (not a voltage-only meter) is the only way to actually know your state of charge on lithium.

Power
☀️ Solar Panels & Charge Controllers
Rigid panels are the most efficient and longest-lived; flexible panels save weight and skip roof penetrations but run hotter and shorter-lived. Size total wattage to your actual daily draw, not a round number.
Renogy 100W/200W Rigid Panel
The most common RV rooftop choice -- good value, easy to source matching panels later.
See on Amazon →Flexible panel, no penetrations
For adhesive-mount setups where you want to avoid new roof holes -- expect a shorter service life than rigid.
See on Amazon →MPPT charge controller
MPPT, not PWM -- meaningfully more harvest per panel. We install Victron SmartSolar on every professional build; it's also DIY-friendly for a self-install.

Power
⚡ Inverters
A modified sine wave inverter is fine for basic loads (lights, phone chargers); anything with a motor or sensitive electronics (CPAP, laptop chargers, microwaves) needs pure sine wave.
Portable pure sine wave inverter
For a simple plug-in setup off a single battery -- no wiring into the coach's DC system.
See on Amazon →Hardwired inverter/charger
Real integration with your house bank and shore/generator charging -- this is a commissioning job, not a plug-and-play part.

Exterior
🏠 Roof Coatings & Sealants
Roof leaks are the single most common cause of RV total-loss water damage. Reseal every fall/spring and after any new penetration (solar, Starlink, vents).
Dicor self-leveling lap sealant
The standard for any roof penetration -- vents, antennas, AC units. Keep a tube on hand.
See on Amazon →EPDM/TPO roof coating
Full-roof recoat for UV protection and small-crack sealing on an aging rubber roof.

Safety
🚨 LP/CO Detectors
These have a real expiration date (usually 5-7 years) printed on the unit -- check yours, not just whether it beeps on test.
Safe-T-Alert dual LP/CO detector
The standard replacement unit for most factory mounts -- direct swap in most rigs.
See on Amazon →Not sure if it's expired or wired right?
A quick diagnostic check during any other visit -- ask us to look while we're already there.

Plumbing
🚽 Macerator Pumps & Composting Toilets
A macerator turns black tank waste into a slurry that pumps through a garden-hose-size line -- useful when you can't back up to a standard dump. A composting toilet eliminates the black tank question entirely, at the cost of more hands-on maintenance.
Flojet macerator pump
The most common aftermarket macerator -- lets you dump through a standard garden hose over distance or uphill.
See on Amazon →Nature's Head composting toilet
The established name in RV composting toilets -- real install prep needed (venting, floor mounting), but no more black tank.

Appliances
🧊 12V Compressor Fridges
A 12V compressor fridge (not an absorption fridge) runs off battery/solar without needing to stay perfectly level -- the standard upgrade for off-grid builds.
Dometic CFX/CRX Series
Dometic-certified brand we install professionally -- several models already in our own shop with real reference pricing.
See in our Shop →Portable 12V cooler/fridge
For a secondary cooler or smaller rigs without room for a built-in unit.
