HI Janalee. I read your other post and will give you my opinions. You self-reported that both you and your husband are elderly. First, I think that its great you want to continue on with the RV lifestyle. But, importantly for your decision regarding this post, about how many more years (roughly) before you might decide to hang up the keys? (NO NEED TO ANSWER HERE.) I'm trying not to be insensitive with this question, but if I were considering the unit you listed above, my time of use of it would be a factor in my decision to buy or not. The water and delam. will be less of a problem for a relative short term use compared to a longer term use. Second, I understand the RV in question has extremely low miles. This is not always a good thing for a motorhome. It means that it has sat around quite a bit, which isn't good for many of the components. Unless the current owners can give you written evidence of appropriate service, you might need to replace many of the fluids, i.e., brake fluid, tranny fluid, oil & oil filter, and may need to have belts and hoses replaced as well. Further, the tires will need to be replaced if they are over six (or so) years old, or if there are cracks in the side walls no matter how good the tread looks or how many driven miles are on the tires. Being from PA, you already know about the required annual state inspection that it must pass. As experienced RVers, I anticipate that you are able to evaluate the performance of the generator, furnace, AC, and the appliances. So, bottom line, if there is no significant structural damage from the delam. and water leak, if you will only use the RV occasionally, if you do not need to sink a ton of money in it for updating fluids/hoses/tires, and the price is right I'd go for it. Besides, you already told us you "love" it.
Best wishes and success in your purchase. Bob
