My buddies 1 year old charmac had the exact same issue.
and he had an axle break away from trailer.
Charmac fixed the axle, and dealer was doing everything they could do to help fix the other issues. He decided at that point to let the dealer fix what they could per charmac, and he sold it.
another charmac in the group continues to have furnace issues, been back to the dealer many times.
I think they (charmac)build a quality product, I've seen older models hold up great for many years.
builds vary yearly from all manufactures.
I’ve owned interstate (not a bad trailer for the 5 years I owned it)
a 2008 mirage(owned it 7 years, would never buy another one)
pace (only had 2 years, real basic enclosed) and last year I ordered a Trails West, and will have owned it a year next month.
Best trailer I’ve ever owned . Fit and finish above most, totally impressed with overall build/paint quality.
It gets used a lot and is holding up above expectations.
Still looks brand new inside and out. Let’s see in 3-5 years how it holds up. So far it’s doing better than any trailer I’ve owned.
just my 2 cents
