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.
United Mobile RV is a mobile shop. We come to the coach — driveway, storage lot, or campground. On-site service: Washington only. Other states case-by-case. Remote help works anywhere. No dealership waitlist and no tow bill for a bay we do not run. Text the location and what already failed, and we will tell you the next step.
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).
🔋 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.
Battery monitor
A shunt-based monitor (not a voltage-only meter) is the only way to actually know your state of charge on lithium.
See on Amazon →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.
Request an AppointmentEpoch V2-T 12V LiFePO4
Drop-in lithium with low-temperature charge protection for cold nights. Epoch is the brand we install.
See in our Shop →☀️ 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.
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.
See in our Shop →Rich Solar 200W rigid panel
The most common RV rooftop choice. Good value, and the same Rich Solar line we sell in our shop.
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 →⚡ 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.
Request an Appointment🏠 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.
See on Amazon →🚨 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.
Kidde CO + propane plug-in alarm
A second alarm that also sniffs propane, with battery backup. Plug it in near the galley. It does not replace the 12V factory LP/CO detector; we swap those on site.
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.
Request an Appointment🚽 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.
See on Amazon →🧊 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
We install Dometic as a Dometic Professional -- 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.
