anyone tried wireless HDMI

Why don't you try and run the HDMI cable and loomex through the ceiling? I've been able to run co-ax, low voltage and 120 volt in the ceiling from one end of our TT to the other without great difficulty. If you take down speakers, AC and skylight bezels, AC grilles and lights, you can fish cable from one access hole to the next access hole until you get where you need to be. If you are stuck part way, you can go up and down inside cabinets and horizontally as well. Upper wall cabinets usually have a 1-1.5" space on the bottom and you can run cables and wiring in there. You can also cut a small hole on the ceiling inside a cabinet to get access.

In 3 TTs now, I haven't been stuck in running wiring through the ceiling to where I wanted it. If you have a go at it, you'll be surprised at what you can do.

Our 2014 KZ TT came with a nice 32" TV that can accept component, composite and HDMI inputs. But the Jensen radio/DVD player only has a composite output. Why do they do this? I will upgrading to HDMI too but will have to ditch the Jensen.

BTW, I just noticed you are in Abbotsford, just down the street from us in Langley. If I can help you at all, send me a PM.

We've been using this http://www.amazon.com/gp/product/B00630WKGI/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1 for a year; working fine.

We had wireless HDMI in our previous coach. Functional distance between units is far less than claimed. We had a 43ft coach. The main unit was connected to the Sat receiver/front TV over the dash. The outside TV in the bin just forward of mid coach worked fine (12ft away through the floor). The bedroom TV struggled at about 25ft away through a wall which included the shower. We would often get pixelation.

We had Actiontec My Wireless TV WiFi / HDMI Wireless HD Receiver

yes.. that is the one in the link in the OP above

I've ordered cables from this place before. Decent prices.

The only problem is this unit will only transmit SD quality video. The OP wants to utilize HDMI to get HD quality video. What he needs is a IO Gear GW3DHDKIT from Amazon. I used it in my previous coach and it worked perfectly, gave crystal clear HD video and 5.1 sound.

Single signal video can not be compared to HDMI or component video signal in signal quality
Just switching to HDMI cable is a big improvement
And I don't think I have ever seen a non scaling dvd player with HDMI output
No reason for HDMI output if it does not upscale

No experience with the device in question, but I have seen similar devices recommended on this forum before

Since the OP does not want to staple an HDMI cable to the ceiling
It's seems a good choice to get the HDMI transmitter

First off, is your source an actual DVD player or a BLU-RAY player? Believe it or not, DVD are not HD, the video is encoded at 720x480 pixels, in a progressive scan format. Newer players offer an up-scaler to improve picture, massaging those pixels to fill a bigger 1280x720 or 1920x1080 screen but your TV has the same feature. That RCA cable is carrying all the video signal there is.

Sound is a different matter, DVD's do have "HD" sound, look for an orange RCA jack on the DVD and the TV, use the red or white end of the rca cable to connect those and your sound quality will improve.

Now, HDMI is a good idea, maybe you'll get a blu-ray player down the road. If you cut the ends off the RCA cable, maybe you can use it to pull the HDMI cable, or at least a string, and then the string can pull the cable. Tie the string into a loop so it pulls itself through again for the future.

Wireless HDMI 'should' work with a DVD player, but you might run into trouble with blu-ray. DVD's are going to be firing at a very low bandwidth (no hd video), so the wireless should handle it. However, you get a blu-ray and try to watch something like Avatar that needs gigabits per second of bandwidth for the video channel, your wireless link is going to barf trying to push all that data.

Reading the review, that unit claims to support blu-ray 3d, which is amazing since that's multiple gigabits per second of data, which means there's some sort of trickery going on, since gigabit wireless is still in the lab, let alone multiple gigabits.
