1971 winnebago travel trailer camper, bought last year dont use it much. Its just been a hunting/project camper. Dont use it as much as I thought I would. Bearings have been packed, new tires. All the plumbing seems to work before I took the sink out water holding tank in the back. Window leaks toward the back driver side. Hook it up to power everything works, except for the furnace and fridge, which is propane
