Even tho I bought the one year extended warranty on my Forest River, Had my Grandson climb up there and seal from side to side the transition seal where both caps are with 4" Eterna Bond.. One year old this week. Other than a hiccup between the dealer/me and factory, all seems to be well. Wanted to buy two tires for my boat trailer and Discount Tire said they wouldn't sell/mount car tires but had to go with trailer tires. Never worn out a tire on a boat trailer, usually they just weather rot. Went with Maxxis rather than the Carlisles they wanted to sell me. LOL
