Well of course first you want to make sure that the tires
, bearings, frame, propane
lines, etc. have all been checked and found to be in good working order. Those are your "peace of mind" items. You may have to replace the battery
. Ours was shot.
As for upgrades, I can tell you some of the things we did: Switched all the running lights
to LEDs and resealed them. Upgraded all the interior lights
to LEDs too. Installed a combination propane/CO monitor and a new smoke detector. Added a larger skylight/vent with a Fantastic fan to the bathroom. Put in a new skylight/vent/fan in the main cabin area too. Got ourselves a free standing 100W solar panel
. Added a small inverter. We ended up having to put in a new power center too. I think it's a smart idea to go ahead and just do that.
We had some rot in the door frame too. My husband removed the door, took it apart and rebuilt the frame. Fits better now too. Shortly after we bought our trailer the hot water heater died. We bought a new one and to save money we opted for the model in which you have to go outside and light
a pilot light
. Oh how I wish we had upgraded to a fancier one where you can just push a button from inside the trailer to light
the hot water heater!
Hope this helps.
