To us, it is all relative in regards to what you will "lose".
Of course, there is the money part of things but if you are in participating in the RV lifestyle, one undeniable truth that somewhere along the way, it is going to "cost" you. In this regard, we are losing about 30 percent on trade.
Why would we take such a loss you ask? Well, there are 2 "major" reasons, and probably another dozen or so lesser ones that I won't list here.
The first is that after living in the trailer for the time we actually were able to, we quickly found out how much our "logical" thinking was off when we decided on this particular floor plan and what we felt we could "live with". We were trying to save some money, but in hindsight, it will end up costing us. We now have a MUCH better understanding of what we not only "want" but "require" in a floor plan and features, which of course costs even more money. But in the end, we know that we will be satisfied with the new one we have chosen and that we have no one to blame but ourselves for trying to cheap out in the first place.
Second, but more important to us was that our current trailer has had failure after failure (a few things more than once) which required our unit to spend almost 3/4 of it's warranty coverage, sitting at the dealership. And there is still an intermittent electrical issue that no one has been able to nail down. But in our opinion, it is a serious enough of an issue that we just are NOT willing to "live with", literally!
So given that we are out of warranty, we are on our own and neither of us feel safe in it, or do we have any confidence that we won't end up spending more time and money trying to keep this one in a usable condition than we will lose on trade in, our choice was clear for us.
So only you and yours can really make the decision as to whether you feel you "gain" more than what you will "lose" and that isn't always about the "money". Everybody's situation is different.
Good Luck in whatever you decide.
