20 year loan for RV?

I bought my 1992 Monaco Beaver Contessa for $15,000 the MSRP on it what's $325,000 it's a luxurious 3208 Caterpillar 4 speed transaxle Diesel Pusher, the body is in seriously nice shape with 0 delamination, solid as a rock handling down the road, I purchased the vehicle with cash and have been living in it since 2013, one of the best investments I've ever made, I will be heading from Virginia to Lake Chapala Mexico in a month or two and know that my rig will be trouble free, the only thing that has given me trouble is the hydraulic jacks that are on it for when I park long term, it's computer controlled,along with the air ride, I had to wire it all bypassing the computer, now it works fine + i have complete remote control. I would not go out and purchase a newer rig that has not proven itself over many years especially the **** they manufacture these days that has computer-controlled engines as well as drivetrain. Not even to mention slide outs. They are like electric windows only more **** to go wrong. :) I could sustain a sizeable EMP hit and the only thing I would probably lose is the radios,short wave,CB,PC and 65" TV if I'm using them at the time. Otherwise my 3208 will keep on tickin down the road as long as I feed it it's funky green juice. As far as finances go, dont belive the hype I have been holding Bitcoin a many a year yes it goes up and down, if I had of sold it at 20K I could have bought back at 3K thats a hell of a gain. Do not try and guess that U will come out ahead because U never know what U're Govt is gonna throw in the mix to screw U over next! :) I'm gonna be an expat an live the chill life down south, U can have this $h!tty american dream all to yourself.
