I was naïve when I bought an old "orphan" beater for too much money. It had newish looking tires with sidewall cracks. It also had a number of other problems that usually go with 20 year old rigs like a generator that leaked gas, furnace that wouldn't work, and amateur fixes to wiring etc. On a short camping trip a tire blew and the flailing steel belt cracked two holding tanks and ripped through some wiring under the rig. It didn't sever any propane lines.
and I didn't lose control. I paid through nose for road service and a replacement tire. We spent the weekend in a seedy RV Park in Puyallup WA waiting for the RV Doctor to open up and plastic weld the holding tanks. We spent some $8K the first year in tire replacement, engine cooling system, engine overhaul, and RV generator work, etc., etc. and finally had a roadworthy reliable old looking leaky RV that we kept for years trying to get some money's worth out of it. We never did have the roof leaks and dry rot repaired properly and lived with the mold smell. These are reasons we try to advise beginners about the foibles of buying a seemingly cheap old RV with dangerous tires. BTW, old RV's bring about $5K when you sell them despite money you invest in them, so invest in repairs and upgrades wisely.
