2023 Thor Windsport 34R Inspection: Low Miles, Serious Problems
Only 12,000 miles. One previous owner. Purchased, serviced, and traded in at the same dealership.
That sounds like a promising start when you’re shopping for a used motorhome. But during my inspection of this 2023 Thor Windsport 34R, I found deteriorating sealant, damaged exterior components, an air-conditioning problem, and two serious safety concerns—including a coach battery that was actively smoking.
It’s a good example of why low mileage and a reassuring maintenance history don’t replace an independent pre-purchase RV inspection.
I’m Mike Murphy, a certified RV inspector, certified RV technician, and owner of Cozy Camper Mobile RV Services. Here’s what I found and what buyers can learn from it.
Low Mileage Doesn’t Tell the Whole Story
This Windsport was built in 2022 and sold as a 2023 model. I inspected it for a buyer who could become its second owner.
The dealership told me the original owner purchased it there, had the maintenance performed there, and traded it back in. The reported mileage—approximately 12,000 miles—was accurate.
But the condition of an RV on inspection day matters more than how reassuring its history sounds.
Service records can help explain what work has been completed. They don’t establish that every component works or that every maintenance need has been addressed. This motorhome had several issues that deserved attention before the buyer made a decision.
A Coach Battery Was Actively Smoking
One of the most concerning findings was in the battery compartment: the main coach battery was actively smoking during the inspection.
There was also extensive corrosion on the battery and inside the battery box, along with evidence of previous overflow. An associated odor was noticeable throughout the coach.
This was an active safety concern, and the buyer needed to know about it before taking ownership. The visible condition alone did not establish the underlying cause, so identifying and correcting that cause would require further evaluation.
An Unsealed Opening at the Water Heater
At the water heater, I found an unsealed penetration where the gas line entered the assembly. The protective grommet and sealing arrangement discussed in the video were not properly completed.
I flagged this because an opening in that location can provide a path for harmful combustion gases to enter the coach. The concern was the installation condition; the inspection did not establish that exhaust gases were actually entering the living space.
This finding needed qualified attention, with the installation checked and corrected according to the water heater manufacturer’s instructions.
It also illustrates why an appliance inspection involves more than checking whether the appliance turns on.
Exterior Damage and Deteriorating Sealant
The exterior had several findings that raised maintenance and water-entry concerns:
Deteriorating sealant in multiple areas.
A crack or chip in the front windshield.
A windshield gasket that was peeling away.
Cracked fiberglass near the rear ladder mounting area.
A rear brake-light assembly that was hanging loose.
The rear fiberglass damage and loose light assembly created potential entry points for water. These conditions needed attention before they could be dismissed as cosmetic concerns.
Much of the sealant appeared old, and I did not see clear evidence of recent resealing in the areas inspected. That does not prove the RV had never received maintenance. It does show that important maintenance needs remained, regardless of its service history.
Even the Horn Didn’t Work
One of the simplest findings was a nonfunctioning horn.
You don’t need to be an RV inspector to discover that. But it’s easy to overlook basic controls when you’re focused on the floor plan, furniture, storage, and kitchen.
A buyer’s walkthrough is a good opportunity to check accessible controls and ask the seller to demonstrate features. Simple checks can uncover problems early, although they don’t replace a professional inspection.
Interior Damage and Signs of Possible Rodent Activity
Inside the motorhome, I found small black cylindrical material on the floor and in drawers that was consistent with possible rodent droppings.
That observation suggested rodents may have been present at some point. It did not establish whether there was an active infestation or how extensive any related damage might be.
Other interior findings included discoloration on the walls and floor, damaged flooring, peeling wallpaper, and unidentified black dust or residue toward the rear of the coach.
The black material was not identified during the inspection, so it should not automatically be called mold. The condition and its source needed further investigation.
An Airflow Upgrade Was Improperly Installed
Both air conditioners had a KoolRV airflow system installed. However, the installation at the front air conditioner had disconnected, leaving the front system effectively unable to cool the coach as intended.
An upgrade only adds value when it is installed and functioning properly. In this case, the presence of an aftermarket improvement did not tell the buyer whether the air conditioner actually worked.
That’s why operational testing matters—even when a seller points to upgraded equipment as a selling feature.
Several Windows Were Fogging
A number of the dual-pane windows showed signs of fogging.
Those windows needed evaluation by an RV glass specialist to determine the appropriate repair or replacement. For the buyer, the important point was to understand the scope and likely expense before committing to the motorhome.
Would You Still Buy This Thor Windsport?
Some buyers would see these findings and keep shopping. Others might consider moving forward if the problems were properly evaluated, repair arrangements were acceptable, and the purchase terms made sense.
My job is to document the RV’s condition and explain the significance of the findings so the buyer can make an informed decision.
For this Windsport, that meant looking beyond the mileage and maintenance story to understand the smoking battery, water-heater installation concern, exterior defects, interior damage, and equipment problems.
The inspection did not determine what this buyer ultimately chose. It gave them information they could use before making that choice.
