I recently purchased the 2001 tioga 26f. It only had 28000 miles and I was worried that low mileage might mean issues. I put about 1000 miles on it without issue. Flat plains driving. Part of my sales agreement was the sellers commitment to allowing rental to someone he already commited too. It has become a frustrating experience.he is travelling at higher elevations throughout Wyoming amd Montana. Day 3 he had issues getting beyond 40 mph going uphill through Wyoming..no power to transmission. Mechanic told him likely all he could expect. Day 5 burns out front brakes, replaces pads, rotors and calipers. Day 6 brakes appear to be still keeping power down intermittently from transmission, has brakes flushed and new brake lines installed and is also told back brakes need replacing along with rotors and calipers and this is done. Believing this will end issues, he has now only driven 30 to 40 minures and says problem not fixed, brakes are heating up and feel like they are still locking up and not allowing him to exceed 40 to 50 mph intermittently. What is left, i am at a loss, this is my first motorhome and i am ready to throw in the towel. Anyone else experienced this or can suggest a resolve, perhaps brakes werent the issue.
