Lake Havasu City · Mohave County

RVs, boat trailers and work trucks

This is the work that defines Havasu. Motorhomes that sat all summer, boat trailers that get dunked every weekend, and trucks that tow in 115-degree heat.

Chassis or house: the split that decides who you call

Chassis means the engine, transmission, brakes, charging, steering and suspension, and a mobile mechanic handles all of it. House means the fridge, roof air, water heater, plumbing and propane, which is an RV technician’s trade.

Getting this wrong is the most common wasted appointment in RV service.

Chassis, and squarely automotive: engine performance and diagnostics, starting and charging, chassis batteries, brakes, cooling, belts and hoses, oil and fluids, steering and suspension, and generator engine service on many units.

House, and a different trade: the absorption refrigerator, the roof air conditioner, the water heater, the furnace, propane systems, fresh and waste plumbing, converters and inverters, slide mechanisms and roof sealing.

There is a grey area. House batteries and 12-volt charging often get handled by whoever is competent with them. Propane appliances should not be, unless the person is specifically qualified.

When you call, say which half the fault is in. It saves a trip for everyone.

Boat trailer repair in Lake Havasu: bearings, brakes and lights

Hot hubs backed into cold water draw water past the seal as the air inside contracts, which is why bearings are the signature failure of a boat town. Annual repacking is the fix, and a hot hub is the warning.

The mechanism is worth understanding because it explains the timing. Tow to the ramp and the hubs are hot from friction and load. Back into the lake and they are quenched in seconds. The air inside contracts, pressure drops, and water is drawn past the seal. Water and bearing grease do not coexist.

It rarely fails that day. It fails a few trips later, at speed, on the way home.

What prevents it: repacking on a schedule rather than adding grease through a zerk, which is not the same thing; letting hubs cool before launching where practical; bearing protectors that keep slight positive pressure in the hub; and replacing the rear seal, which is the cheap part standing between the bearing and the lake.

While the trailer is up, the rest deserves attention too: electric or surge brakes and their adjustment, the breakaway battery that is dead on a remarkable number of trailers, the seven-pin connector and its grounds, and tyres judged by date code rather than tread. See the bearings guide.

Motorhomes after a summer parked

A unit that sat through a Havasu summer needs batteries load tested, tyres dated, brakes checked for seizure, fluids refreshed and a look for rodent damage before the first trip.

Sitting is not resting. Six months of heat and stillness leave a predictable list.

Batteries, both banks. Self-discharge accelerated by heat, then sulphation, which is largely permanent. Load test rather than voltage check, and fit a maintainer for next season.

Tyres. RV tyres age out before they wear out. Sidewall cracking from sun is the failure mode, so the date code matters more than the tread. Check for flat spots and set pressures cold and to the load.

Brakes. Surface rust and seized calipers, especially if it was parked with the parking brake on. On a heavy vehicle that is not minor.

Rubber and fluids. Hoses and belts age by calendar here. Used oil is acidic, so change it before the first trip if it was not changed before storage. Fuel degrades and causes running faults that get misread as ignition problems.

Rodents. Wiring looms and insulation are nesting material, and the damage stays invisible until a circuit stops working. The wake-up guide goes through the whole list.

Fleet and work trucks: the argument is uptime

For a small fleet the case for mobile service is uptime rather than distance. Vehicles serviced in their own yard before the day starts are not sitting in a queue, and several on one visit spreads the call-out.

If you run two to ten vehicles the maths is different from a household.

A truck in a shop queue is a truck not earning, and that cost dwarfs any difference in labour rate. Servicing in your own yard, early, on a schedule you set, removes the queue entirely.

• Batch the visits. Several vehicles on one trip means one drive, shared.
• Service on your downtime. Early morning, which in summer is also the only sensible time to work outdoors.
• Keep records per vehicle. Knowing which truck is due for what prevents both neglect and duplicated work.
• Fix small things early. On a work vehicle an unplanned failure costs a day, not a repair.

Ask about a standing arrangement rather than one-off calls. Predictable booked work is usually reflected in what an operator charges for it.

Before a trip, and before the summer

A pre-trip chassis check covers fluids, belts, hoses, cooling, brakes, tyres including age, both battery banks and lights. A pre-storage service is about leaving nothing to deteriorate over a six-month summer.

Before a trip. Oil and coolant level and condition, belts and hoses, radiator and fan operation, brakes, tyre pressures and date codes, both battery banks, all exterior lights, and the trailer connection if you are towing. An hour, and the cheapest hour of the trip.

Before storage. Fresh oil, because used oil is acidic and sitting in a crankcase for a Havasu summer is not neutral. Fuel stabiliser. Batteries on a maintainer rather than left flat. Tyres inflated and covered if possible.

Coming out of storage. This is where the failures live, and it is the busiest week of the year for this kind of work. Booking ahead of the season rather than after everyone else has arrived is worth real money in October.

Weight, tyres and load ratings on a heavy unit

RV and trailer tyres fail from age and overloading rather than from tread wear. Pressures must be set cold and to the actual load, and the date code matters more than how much tread is left.

Tyres are the single most common cause of a serious roadside incident on a heavy unit, and almost all of it is preventable.

Age beats tread. A motorhome tyre with most of its tread can be dangerously old. Ultraviolet light and heat break down the sidewall compound, and in this town that process runs fast. The date code on the sidewall gives the week and year of manufacture, and for a unit that sits in the sun it is the number that decides replacement.

Load, not maximum. The pressure moulded into the sidewall is the maximum, not the recommendation. A heavy unit should be weighed, ideally per axle, and the pressures set from the manufacturer's load and inflation tables. Underinflation under load builds heat, and heat is what destroys a tyre.

Cold means cold. Set pressures in the morning before driving. Pressure read after an hour on the road is higher and tells you nothing useful.

Look for cracking. Fine cracks in the sidewall or between the tread blocks mean the rubber has aged out, regardless of depth.

Covering the tyres during a summer in storage costs very little and adds years. So does moving the unit occasionally rather than letting it stand on the same contact patch for six months.

Storage yards, access and what slows a visit down

Most delays on stored-vehicle work are access rather than mechanical: a gate code nobody has, restricted hours, a unit boxed in, or no flat firm ground to work on. Sorting that out when you book saves a wasted call-out.

A large share of the vehicles here live in storage yards for part of the year, and the yard is frequently the harder half of the job.

What to establish before the appointment:

• Access. Gate codes, opening hours, and whether a contractor can enter without the owner present. Some yards require the owner on site, which changes the scheduling entirely.
• Position. Can the unit be reached and worked on where it stands, or is it boxed in by other vehicles? Moving something that will not start is not a small task.
• Surface. Gravel and sand are common in yards and neither is safe for jack stands under a heavy unit. Firm level ground matters more the heavier the vehicle is.
• Power and shade. Neither is essential, and both make a summer visit go considerably faster.
• What else is there. If two vehicles and a trailer are in the same yard, one visit can cover all of them.

Five minutes of this on the phone is the difference between a productive morning and a mechanic standing at a locked gate with your battery in the back of his truck.
