No doubt older trailers were built better than the ones today (generally speaking). However when you buy an older used trailer you are inheriting all the handy work, repairs and damage from previous ownership. Not a deal killer but it means the inspection process needs to be much more in-depth and you need to know where to look and what you are looking for. Most everything can be corrected and helps with getting them to lower the price. The #1 thing you want to walk away from is WATER DAMAGE from the roof, seals and plumbing. Small leaks that were corrected quickly don’t result in water damage but many RV owners don’t know something is leaking, or if they let it go for too long before trying to do something about it. Many times their attempted repair doesn’t work because they either don’t want to spend the money or don’t understand what they are dealing with. Run away from trailers like this because the water damage you see is usually just the tip of the iceberg.
