I bought old and used, to see if I really liked RVing, and now nearly 4 years later, I have no regrets. I've put money into mine too, and I am enjoying every penny of it and having a blast!
It's like a hybrid RV, half of it old, half of it new, but for the price of used.
I've been able to upgrade this and that, more to my liking, customize a few things to suit me, so I've traded some of the 20 year old equipment for newer stuff (but only if the old stuff was ready to go) but it's stuff I picked out and liked. Of course I've had my share of surprises thrown at me, like when the poop tank tried to fall off, but I like to keep things repaired, so that I can go have fun without too much falling off.
All in all, you can get a lot of bang for the buck with old but functioning used motorhomes.
When I figure out the 46 months I've lived fullime in mine plus traveled, divided by the purchase and the repairs, it's been a huge bargain all around. My insurance and taxes are cheap, my systems are simpler and easier to repair or maintain, there is a lot of good stuff about owning old and used.
I go to the same beautiful parks and camp right next to folks that spent a zillion bucks.
I see many folks in far flung parks resurrecting older RV's and having a blast.
There is less fear too in some ways. I've been to some jaw dropping beautiful places because I wasn't afraid to take my baby there. I've made a little dent and scratch here and there while I was learning to handle my rig... oops...
But I've had FUN FUN FUN.
I saw your pics, looks beautiful for her age and in great shape, go take a good look at it and test out the systems. Used rigs are priced all over the place and sometimes folks sell them right after they've fixed everything and you're good to go with their loss being your gain.
I've got my rig so comfy and organized for my style of living, that I shutter to think about trading her off. I've even had 2 different folks offer to buy it this past year, and I wasn't even offering to sell it.
