And yes, flexibility is a big factor in deciding on the pop-up camper, especially since I'll often be towing, either the 3 horse slant, or occasionally a 3 rail dirt bike trailer. Or, if just one dirt bike, I can use a hitch carrier for the bike. I also love the idea that I can store it in my garage if needed, otherwise I'm thinking it will be stored in the back yard. I love that it takes up just that much less room then a regular hard side camper.
And just last night it occurred to me that I'll want a way to get to the store to restock groceries when we are at horse events and I won't want to break camp. I may have to buy a little scooter like a Yamaha Zuma, or maybe get my kids DRZ125 plated for quick trips to the store. More toys. Yeah me!
That may mean getting a front hitch mount setup for the truck for when I'm towing the horse trailer if I want to bring a scooter or little dirt bike. I'm also going to go out and study our horse trailer, there is some room up front between the leading edge of the tack room and the tongue platform (for lack of a better term). I'm wondering if I can fit a rail crosswise there and secure the bike on it. I know it will fit and I think the trailer frame would be strong enough, just not sure how it will impact the turning radius of the truck/trailer combo. Would be adding weight to the tongue too, but I don't think it will significantly affect anything as its a three horse trailer but we only ever haul one horse in it (plus all the tack, supplies, hay, etc).
Lastly, I hear you on the getting sick of the project. The last 5% of any large project is always the toughest. Hang in there, you are so close!
