Someday I will post up pictures of the mods we did on our Jayco. In the back there is a full-size bed. First thing was we replaced the mattress with a new one. Second, I removed the bunk bed above it to make more room. Then, after some discussion, we pulled out that huge cabinet they put in the bedroom, too. You can hit your head on that thing easy.
Then...I installed a shelf on the bedroom wall, the wall toward the front of the trailer, and mounted a TV/DVD combo on the wall, plus a small shelf with a lip on the front. I hung speakers on the wall, just small powered computer speakers, and hooked them into the TV. When you do this, they will connect to the TV through the headphone jack. So...when you turn up the speakers, you can then control volume through your TV remote. Works great. Lay in bed, watch whatever.
I installed a 750 watt inverter into the front storage compartment, the one behind your hitch, and then ran a power line from it to the dining table area where the cable outlet is. And another power line to the bedroom. By doing this, you can run some limited AC power to your bedroom for the TV, and another one to the dining area for a TV there as well. Now you can have TV in both locations without running a generator. (We have a four battery system installed in the storage area up front, totaling 400 amp hours.)
Then I installed a solar panel, just a modest 50-watt panel with a controller, and ran the power down to the battery system. This cuts down significantly how much we have to run our portable generator. 400 amp hours will carry two TVs, your lights, spark and fan for the furnace, water pump, etc all night and beyond easily. Then in the morning, you just fire up the generator to run the microwave, hot water, etc and charge up the batteries at the same time.
We mostly do not camp in RV parks. We are 90 percent on the boondocking thing, so I tried to set us up for that. And even though the trailer is only 17 feet, it still has virtually everything some of the larger trailers carry. It was a 30th anniversary version by Jayco and they did a nice job on it I must admit. Plus the last owners remodeled nearly the whole thing, replacing the electrical system, the hot water tank, flooring, entire bath, a bunch of stuff. But they sold cheap when the storage place they used doubled the rate on them. I think the wife wanted the husband to sell.
Last week we took it to a place called Eagle's Nest Vista in Washington state's Ahtanum State Forest. Six thousand feet up near Darland Mountain. Couldn't go further because there was snow ahead.
We are totally crazy sometimes. I swear.
