The Spring Shakedown That Should Happen Before the First Trip, Not During It

The pattern is familiar. Coach comes out of storage, gets loaded, gets driven somewhere, and something is discovered three hundred miles from home.

Almost everything found that way was findable in an hour in your own driveway. Here is the order that catches the expensive things first.

1. Roof and seals, before anything else

Every penetration, every seam, in good light. This is first because it is the failure mode that damages everything else and because eight months of sun has just happened to it.

Looking for: shrinkage, cracking, chalking, hardness, separation at any edge. Any two of those across multiple penetrations means a reseal before the trip, not after. Recoat and reseal runs $750 to $4,500 at 4 to 20 labor hours.

While you are up there, feel for softness underfoot. A spongy area means decking, which means a bigger conversation.

2. Tap test the walls

Twenty minutes with a coin, in a grid, both sides, front cap and rear.

You are listening for the change from a sharp tap to a duller, hollower one. Mark it. If you find debonding, note whether there is staining on the interior side at the same location, because dry debonding and wet debonding are different repairs.

This is second because a wall that debonded over the storage period tells you the roof failed over the storage period, and finding both together is more useful than finding either alone.

3. Slide operation, watching and listening

Cycle every slide fully, twice, and pay attention.

• Does it move evenly, or does one side lead?
• Does it hesitate at any point in travel?
• Does it sound different from how you remember?
• Does it seal along its whole length when closed, or is there a gap at one corner?
• Is there any staining at the floor edge inside?

A slide that hesitates or leads on one side is telling you the opening or the room has moved, and forcing it repeatedly is what turns a mechanism job at $500 to $8,500 into a structural one at $1,500 to $7,500.

If it is bad enough to worry you, stop cycling it and get it looked at. A slide that strands the room extended on a trip is a considerably worse day than one that gets diagnosed in a driveway.

4. Awning, extended fully

Out through full travel, looked at, back in.

• Fabric condition, especially at the hems and stitching
• Arms straight, pivots not sloppy
• No cracking at castings
• Retracts fully and evenly without bunching
• Mounting rail fasteners tight, and no staining on the sidewall below the rail

That last one is the important one. Elongated awning rail fasteners after a wind event funnel water into the sidewall laminate, silently. Fabric replacement runs $400 to $2,500 and arm or motor work $500 to $3,500, but a rail problem is a sidewall problem and it is worth far more.

5. Water system, then a real water test

Fill, pressurise, and then leave it under pressure for an hour while you look underneath and inside cabinets.

A weeping fitting is easy to find under pressure and nearly impossible to find while driving. Fresh water system repair runs $400 to $6,500 and pump and valve work $250 to $3,500.

Then a genuine water test on the exterior. Hose on the roof, the seams, the slide openings and the window perimeters, with someone inside watching. This is the single highest value hour available and almost nobody does it.

6. Electrical and appliances

• 12 volt systems and lighting
• Battery condition and charging, because heat storage is hard on batteries
• Inverter or converter operation
• Solar output if fitted, checked against what it should be producing
• Every appliance, run properly rather than switched on and off
• Generator started and run under load, not just started

Electrical work is at our $260 per hour mechanical and electrical rate. 12 volt systems $250 to $4,500, battery and charging $350 to $12,000, inverter and converter $500 to $8,500.

7. Tyres and running gear, visually

UV cracking on sidewalls, pressures, and dates. A tyre with a good tread and a 2016 date code and cracked sidewalls is not a usable tyre.

The two findings that mean stop

Soft floor or soft roof underfoot. That is structural and it is progressive. Driving on it makes it worse, and a soft floor at a slide edge with the slide operating is doing damage every cycle.

A slide that binds or stalls. Because the failure mode from here is the room stranded extended, and that turns a scheduled repair into a recovery.

Everything else on this list can be planned. Those two should be looked at before the coach goes anywhere.

Our RV systems evaluation is $150, covers roof, slides, seals, water, electrical and generator with moisture readings and a written report, and is refundable as a credit against an authorized repair. On a coach coming out of a long storage period, that is a cheap way to start a season.
