Weekend and Seasonal RV Owners

A coach used three or four times a year spends the overwhelming majority of its life parked, and parked is where the damage happens. Sun on a roof membrane and on gelcoat for ten months. Sealant cycling through a Southern California temperature range with nobody looking at it. Rodents in a wiring harness. A slide topper collecting debris. Tire flat spots and a house bank slowly discharging.

None of that announces itself. A coach that was fine in September is fine in the same way in April, right up to the moment somebody extends a slide, runs water through the system, or looks properly at a corner seam. The failures are cumulative and silent, which is why the discovery moment is nearly always the same: de winterisation, a fortnight before a trip.

Coastal storage adds corrosion to the list. Salt air on fasteners, frames, jacks and aluminium trim does slow steady work, and a coach stored within a few miles of the water ages differently from one stored inland. Rust treatment and anti corrosion coating runs $400 to $3,500, and it is the cheapest item on this page relative to what it prevents.

The classic sequence runs like this. Water goes into the system, a fitting that froze at some point in January lets go, and there is water in a cabinet. Or a slide comes out and the fascia has separated from the wall at the top edge. Or the floor at the slide opening flexes underfoot in a way nobody remembers from last season.

That is the point at which a seasonal owner discovers a problem which has been developing for two seasons, and it is also the point at which the sudden versus gradual question decides whether an insurer is involved at all. Water that entered through a joint nobody maintained for four years is deterioration whatever it eventually damaged, and this shop will say so rather than write a supplement that a reinspection will find.

The practical answer is a look before the trip rather than during the panic. A pre purchase inspection with a written report runs $400 to $1,200 and it is exactly the same work whether you are buying a coach or checking your own after storage. Winterisation and de winterisation runs $250 to $750, and having it done rather than improvised is what removes the frozen fitting from the story.

A seasonal owner rarely wants the best possible repair. They want a coach that is sound, safe and presentable by a specific Friday, and the honest conversation is about which of those three the calendar allows. That is a legitimate way to buy a repair and it deserves a straight answer rather than an upsell.

So bring the date first. Some work can be staged: make it watertight and serviceable now, do the cosmetic finish in the autumn when the coach is going back into storage anyway. Some cannot, because structure precedes everything and refinish is real shop time. A full detail runs $500 to $3,500 and will do more for how the coach looks on a Friday than a partial refinish rushed to make a date.

Spring is the pinch, and it is worth saying plainly. Everybody de winterises in the same fortnight and calls in the same week. A coach brought in during February for work that will be needed in May gets a calendar. A coach brought in during the second week of May gets a queue.

This is the question a seasonal owner actually has and rarely asks, so it is worth answering directly. A coach used four weekends a year, worth a moderate amount, with a soft floor and a delaminating sidewall, may not be worth what it costs to put right. Water damage, delamination and soft spot repair on a trailer runs $750 to $18,000 or more, and the top of that band exceeds what some units are worth.

A shop with a bay to fill has an obvious incentive not to raise that, which is precisely why it belongs on the page. Nothing here is priced below $500, and some repairs are not worth doing even when somebody is willing to pay for them. Where that is the case we say it, itemise what the repair would involve, and let the owner decide against a real number rather than a hope.

Where it is worth doing, the arithmetic usually favours doing it properly once. A roof recoat over decking that has already gone soft seals moisture in rather than out, and a second attempt costs more than the first one done correctly. Roof recoat and reseal runs $750 to $4,500 and a membrane replacement runs $3,500 to $18,000 or more, and the decking is what decides which of those two the coach actually needs.
