First problem you're gonna face is finding (new or used within a few model years) anything with the quality of what you have right now. That is, for a price you would be willing to pay. LOL, finding is easier than paying, that's for sure!
If I recall correctly, those Citations are no longer made, but extremely highly regarded by those who do own them.
A quandary for sure.
I do suppose that three more years on that age of a unit is not going to make a huge difference anymore in its used value. So to me, I'd keep it for now and just see what you actually end up doing as far as travel/camping. Then, if you find out you do want to travel/camp more then the option to go with a different unit will still be available.
ON EDIT: got curious, so I went to the NADA site to find an approximate value to your Citation.
One has to look under the manufacturer General Coach West to find this model, as I think this one covers the units made in Canada.
So I zeroed in on 2003 Citation Supreme 34 RLTS. I didn't click on any options, as I have not the slightest clue what your trailer is equipped with.
I found low and average retails prices of $18,140 and $21,860.
Mind you, I have no idea if this is in Canadian or US dollar amounts. But at least it is a reference point for your information. And, as I said earlier, three years will drop the value for sure, but considering where it is now, to me, its not gonna be a game changer in what one would do.
I am actually in the same boat as you as I have a 2003 Hitchhiker Discover America Quad Slide that I am thinking of replacing. New units are nice, but pricey.
Best of luck.
