Check the axles, bearings and tires. I almost got burned, I never checked the axles, the trailer was always backed up to a garage door or another trailer. I realized just before my first trip with it as I pulled it forward that all 4 wheels were kicked out on the bottom. The one thing that saved me was I told the salesman that I wanted all the axles components checked before we will take delivery, I made sure he wrote it down and we signed off on it. I suggest you do the same and include the roof, water and electrical systems (ac and dc). There are a lot of components that could fail and some rv owners don't keep up on maintenance. Make sure the furnace, air conditioner and thermostat work too. Look in every compartment to see if you see water stains or moisture. One thing I did hear was some frame problems on pilgrim trailers, i believe they were lippert frames but can't be for sure, I almost bought an open road and that leads me to my final thought. Do not allow the dealer to sell you a trailer that is too heavy for your truck, this happens far too often. Every rv dealer I have ever worked with told me what I wanted to hear so I would buy what they were selling. I almost bought that 37' open road with a 17,000lb GVWR, way too much for my truck (2001 F350 single rear wheel diesel). I recommend you tell us what truck you plan on using, it will give you an advantage.
