Destination Trailer Repair for Long Term Sited Units

Everything a touring RV avoids by moving. A destination trailer parked for a season has one elevation permanently in shade and one permanently in sun, sits on jacks or blocks that trap moisture at fixed points, and often has a deck or an awning structure attached to it.

The result is asymmetric damage. The sunny side chalks, the sealant on that side hardens years before the shaded side, and the roof membrane over that half ages faster. The shaded side stays damp, grows biological growth in the sealant beads, and the wall behind it never fully dries after rain.

Owners who inspect the accessible side and assume the other matches are the ones who arrive with a subfloor job. Roof recoat and reseal is posted at $750 to $4,500 across 4 to 20 hours, membrane replacement at $3,500 to $18,000 across 20 to 80 hours, and water damage restoration at $750 to $15,000 across 4 to 60 hours. See roof repair.

Because destination trailers use large residential style windows to make the interior feel like a room, and residential windows are not RV windows. An RV window is a clamp ring design engineered around a wall of known thickness, sealed with butyl, and intended to be removed and rebedded periodically. A residential unit is set in a frame and caulked.

Caulk is a maintenance item with a finite life, and on a trailer parked in Southern California sun it hardens, shrinks and pulls away from one edge. Water enters at that edge, runs inside the wall and shows up somewhere else entirely.

Window and frame reseal and replacement is posted at $250 to $3,500 across 1 to 14 hours. On a sited unit it is worth doing on a schedule, particularly on the elevation that takes the afternoon sun, rather than waiting for a stain to appear inside.

Size and duty cycle. Destination trailers carry very large slide rooms, sometimes a full length living room wall, and those rooms are typically deployed once at the start of a season and retracted once at the end. That is the opposite of the touring pattern, and it causes its own problems.

• Seal compression set from months in one position, so the room leaks in the other position.
• Mechanism seizure from lack of use, which is more common than wear on a slide operated twice a year.
• Roller and pad flat spotting from a room sitting in one place under load.
• Debris accumulation on the slide roof, which the topper is supposed to prevent and often does not after a season under a tree.
• Frame twist from the trailer being levelled once and then settling on soft ground over months.

Slide out mechanism service is posted at $500 to $8,500 across 3 to 35 hours, seal replacement at $400 to $3,000 across 2 to 14 hours, and topper replacement at $450 to $1,800 across 3 to 8 hours.

Often, because these units are used like a second home and the interior is what the owner actually experiences. The structure is a standard RV shell, so the constraints are weight and wall thickness rather than anything unusual, and the results can be very good.

Common work: replacing the original flooring throughout, refacing or replacing cabinetry, upgrading countertops, changing out furniture, and reworking lighting. Full interior remodel on a camper class unit is posted at $1,500 to $35,000 across 15 to 150 hours, flooring replacement at $750 to $9,500 across 6 to 40 hours, cabinetry work at $500 to $7,500 across 4 to 35 hours, and countertop repair or replacement at $500 to $7,500 across 4 to 35 hours.

The one caution is weight. A destination trailer still has to be towed, and stone countertops and tile floors add up fast. That gets discussed at the estimate. See interior remodeling and the prices page.
