We're blessed with mostly dry weather here in the summer, so if we have to camp in the rain, it can get noisy. We bring earplugs and wear them when things start to drip. We've experienced some dripping/running sounds while camping at the beach in heavy fog. I know that nothing leaks, so I can go back to sleep
. We get condensation on the walls with 4 people sleeping/breathing in the TM, especially if it's raining. We just wipe down the walls when they need it, and sometimes place dry towels at the bottom of the walls in the rear bed (that seems to be the worst place for the condensation).
We have Goodyear Marathons and keep them at 50 PSI, but have also experienced some bouncing on some roads. What kind of tires to do you have?
