For me to have kept track of the hours. Would have made it more like working (at a job). What's the fun in that? I wanted to have it done at a certain time. But because of life and health throw in's, it's taking me longer. Now I do it with the attitude "It'll be done , when it's done". That being said... If I was planning on building them to sell, I would have kept a great log of time. Like I did when I was working building custom cabinets..
A few have mentioned the cost (budgets) here. We wanted one. Just never seemed to be in the cards to have enough at one time to buy one. Thought about setting up just a savings account, little in it each month, til we had enough to buy one. Then figured to construct one would work better for us. Do it on kind of an installment plan, little here, a little there. And have so much fun building it the way we wanted it, not buying what someone else thought it should be.
Well, still working on it, enjoying it when I do and when my health lets me...
All my receipts are in one desk drawer. Couple months ago, I decided to add them up,,,, immediate thought,, WOW, I spent that much... and I'm not done... (Though remember) I'm doing this on the installment plan..build as I go (available funds and time)..

If I'd done the savings account idea, I wouldn't have enough yet to buy one. And I have been enjoying myself so much, building it myself... Priceless !!!!!!!!
Not to forget, I have met so many great people through this forum, that I wouldn't have met, if I had just bought a little camper... (looking forward to seeing them on here and eventually meeting one day when this little camper is campable)
Sorry for gettin a little winded here,,, to much coffee, so early this morning... never a good thing..

Have fun, make it yours, and enjoy it when it's done. (Well campable, because It will never be done, hahaha)
