Mine also a 79 Acorn - floor and door frame in pretty good shape . Used SS screws + nyloc nuts and butyl rubber tape to rebed ALL windows
and hatches . Inside painted with Rustoleum when I got her - only occasional touch up req'd .. Frame and axle
seem to be much better than I have a right to expect . Replaced Stove and Ice Bx with Dorm size Refrig . Took out the water tank (one that does not leak is rare ) Rewired to use a 12 v dry cell with LED lights
- and use the 1 lb cans of gas with the stove . ( no weighty battery
- the 12 v lasts a yr or 2 -- and a 1 lb can of gas lasts a week or more ( Walmarts are ubiquitous - so I don't haul much weight
at all ! ) Thinking of moving up a notch - but this thing is such a pleasure to move around on a dolly .. and other wise suits our needs . Used a marine hatch to replace the center door beneath the bunk bed shelf in the forward end - fits like it was made for it . Used Perco flooring - would use vinyl tile next time ( that 1/4 in is rather critical ) Replaced the pc of carpet under the " table "( which was screwed down to 1x2 PVS rails placed along the FB glass molding's. Rewired of course using marine tinned #12 wire from West Marine
( which ended all electrical
problems - probably overkill -- but worth it ) and added marine 30 Amp SS covered AC trailer hook up ( again probably over kill - but for 12 bucks ! ) Got a memory foam mattress topper - don't know if I like it yet. Had curtains made up by Vista Print copying onto banners some of favorite art -- which like quite a lot . ( Note to further preserve the floors - and any other wooden parts - Slosh - Soak - whatever with a solution of warm water and Copper Sulfate - which you cannot purchase - except at every Home Depot or Lowes - as Root Kill - a product used to kill the tree roots in home sewer / septic lines - Its a blue crystal - wear gloves and don't drink it ! Works a treat - dang floor will out live me ( I used it on the topside of the floor where possible ). I also replaced the factory furnace
with a small thermostatically controlled elec heater .
The " Keep it simple Stupid" principal seems to work well for me for obvious reasons .
Hope to be at Eggbeaters in NY in July - see ya thar !
