When we ordered our Hallmark Ute I requested a number of additional 12-volt accessory outlets and USB outlets in every possible place one might ever be needed by us (a few) or anyone else in future (many more), as the desire to plug in keeps increasing. Each is on its own fused circuit with a switch to each to cut power to reduce parasitic losses some USB ports consume. By build time they found a sort of duplex-looking combo outlet with a single 12-volt accessory outlet next to a round and similarly rubber capped dual USB port. One USB is the basic 5-volt, 5-watt (1-amp) type; the adjacent one is 5-volt, 10-watts (2-amps) for newer devices. I also requested coaxial pre-wiring and bracing for a TV, with one cable to outside for RV park hookup and another through A/C vent opening for any future antenna. We don't use it yet but it might make a good selling point later. And, re A/C, if you don't order it, at least get the bracing and pre-wiring, something every RV should have for future-proofing. I also requested wiring to each corner for electric camper jacks despite my ordering manual jacks. When being built and everything is open, every wire you might dream of us easily routed at little additional cost. Consider some of these, as such a basic order change won't affect your build now and might not incur much cost.
Re USB parasitic power loss, it didn't amount to much and with 300 watts solar and two 6-volt AGMs in series, we could run the Nova-Kool refrigerator indefinitely in sunny weather.
A note re solar panels:. One blocked the SiriusXM antenna on truck so we complained to Sirius and they sent a dash-mount unit that broadcasts the low-powered FM signal to truck antenna. I mounted their supplied Sirius antenna to right front corner of fender via a small bracket attached below side of hood. On a non-metallic camper that would otherwise not block SiriusXM on truck, placement of solar panels on camper roof to avoid signal blockage is an option vs the add-on receiver.
Another camper item: I ordered a Jensen AM/FM/SiriusXM-ready/weather-band stereo and had it delivered to Hallmark for their installation and hookup to the speakers they often install on many rigs, anyway. Hallmark ordered an AM/FM/SiriusXM antenna but I don't recall brand. Watch out; some are XM-only. After receiving camper, I ordered a SiriusXM compatible tuner and mounted it behind Jensen receiver.
So, lots of options for you, including confirmation of what camper manufacturer would order and what you'd order and have shipped to them.
