RV repairs
I've spent most of my life working on vehicles, so I can, usually, handle a wrench. My '89 Coachmen Horizon is based on a GMC 3/4 ton van. I've got a couple if issues I need to address before I take it on the first trip in a few weeks.
First up, my back end is droopy. No, I pull my pants up. Most of the time I wear bib overalls anyway. However, my rear springs have lost some of their arch. Rearching the springs would set back my travel. I see two options. Air bag assistance or air shocks. Air shocks are a known entity and I can rig up a pump and pressure valve to adjust pressure from the drivers seat. A shock set will run me around $80. The second option is an air bag assist. I've never run this before and friends talk about the need for two air fills or a master fill control panel. With the air bags on a single fill line, a twist of the rear axle will force air out of the upper bag into the lower and twist the axle severely. Air bags will run around $490 plus installation parts.
I'm leaning towards air shocks due to lower initial cost, shorter install time and ability to adjust on the move. (i.e., add a little air when dragging on pavement.) What says the general consensus here?
My second issue is the spare tire carrier. I have two trailers with an enclosed trailer bought for logistics support (extra fuel, generator, small motorcycle) bought to tow behind the RV. Both trailers have jacks that will hit in a left turn. I load my trailers with a 55/45 balance rather than 60/40 so an extension may not be over stressed. Other options are replacing the jack with a fold up version or raise the spare. The spare sort of blocks the left rear tail light anyway. A hitch extension seems to be the most feasable. What does everybody think?
