A neighbor wants to pay me eighty dollars worth of pesos for my year and a half old GOHNER group 34. I am going to mount a 31 AGM behind the front seat on the "transmission tunnel". In a battery box. Run a 1 gauge cable around to the portside door sill then forward to the firewall and with a bulkhead pass-through exit into the engine compartment. The 1-gauge will join it's smaller brethren where the 34 used to reside.
When I do an el-cheapo sleepover behind a gas station, I can run the Endless Breeze and BiPAP and not have a worry in the world. On a five day journey home, 3-4 of the nights are spent at all night gas stations. What's a few hundred dollars between friends? When I arrive in Gracias Honduras, or El Limon Nicaragua, the AGM will damned sure not quit on me. When I croak, Jesús can use the AGM in his panga for a decade or two. If that sucker can -NOT- live through at least five 34 batteries I'll snort a pint of 1.275 That is a guarantee. 34's cost A HUNDRED THIRTY FIVE DOLLARS EACH DOWN HERE.
