Veebyes,
In my opinion, I doubt you'll be able to get any extra from the sale of the RV if it has all of these extras.
As to whether all of that will attract or deter potential buyers, I think that will depend upon the buyer.
Hear are my thoughts. Personally, as someone who has had our first motorhome since 2004, I would appreciate the spare parts & tools, but not so much camping gear as we already have that stuff. However, yours might be better than what we have, so that could be my decision. Extra chairs, grill, etc. could always be put to use at our regular house or given away to friends & family. But to be honest, I would see these as "added perks", not something I'd be willing to pay extra for, or not too much, anyway. (And yes, I too, carry a spare water pump with me. It's the difference between having water flowing in 15 minutes and waiting hours or days.)
I suspect other seasoned RV'ers might be similar, as they KNOW things will break and if they've been doing the maintenance on their own rig, they'll appreciate getting a head-start on the spare parts base. At this point, they most likely don't know what they're getting into.
As to complete newbies, as we were back in the early 2000's, I would think they would appreciate the camping paraphernalia as they probably have little. However, I think that most might be deterred if there were too many tools or spare parts available. Maybe a few, but most of them don't fully realize that there will be maintenance that needs to be done. In fact, I think we can split this pool of potential buyers again. Those who do or will do their own maintenance, would see more of a value on parts & tools. Those who don't know which end of a screwdriver to hold will definitely NOT be impressed with tools & spare parts, and most likely would be deterred.
For all of the above, I would expect that things be neatly organized in bins & plastic boxes (for smaller items) with labels. If it looks cluttered and unorganized, that looks like you just want them to throw your stuff away for you.
Knowing you'll be on a tight timeline, perhaps you might just list the rig itself in any ads you place, and perhaps a slight mention that standard items needed for camping are happily included in the price. You can decide what those might be. But don't list too many as to deter those who might already have chairs, a grill, mat, or whatever else you list.
Once you have potential buyers, you can hopefully get a better sense as to whether or not they're seasoned RV'ers, or novices, and adjust your sales pitch and the included items based upon that. Some people are minimalist and probably won't want anything. Others, like us, tend to be "hoarders in training"
๐ and would probably take anything of value IF we thought someone could use it. (I HATE seeing things go to the landfill that still have some life left in them. Hmmmm...maybe you should advertise it as a "Hoarder's Special". LOL ) Whatever isn't taken, hopefully you can donate it or just pay to have it all disposed of properly.
Good Luck,
