Trip computer addon?

[AverageGuy]

I have a Greyhawk 29 MV that replaced a 37' Georgetown Two things I miss are the washer/drier and the trip computer. I really liked the ability to know how many miles of fuel I have left. While I can kinda guess based on the fuel gauge, I like to have a firm number in mind. It saves excessive fuel stops.

Are there any addon trip computers that won't break the bank? I googled for info and saw some discussions of diesel devices but nothing for gas engines.
I'd roll my own but it's not as easy as it once was with fuel running both from the tank and back into the tank which requires two flow meters.

Thanks,
Jim.

Scangauge II and Ultra gage are 2 I have used. SGII was much easier for me to use and calibrate to fuel usage. Right now I am within 3 tenths of a gallon from what I put in to what the SGII says it used. Never tried the Scangauge E but if you are on a budget and/or a trip computer is all you want might be a good choice.

UltraGauge OBDII Scan tool & Information Center

amazon and parts stores carry both.

EDIT. Both are for gas and diesel vehicles with a OBDII connection. I used the UG on my gas Toyota but again I found it cumbersome to use and to calibrate actual fuel usage.

Thanks, it appears that they either discontinued or can't build the E model since no one appears to have them in stock.
That's what I was looking for.

I have a wireless OBDII sending unit, and I use an app called TorquePro. Works great, I an configure it how ever I please. Free version will do everything you want.

Interesting, I have a 2022 29MV as well and the built-in display (as wimpy as it is) does stated how many miles approximately until empty as well as fuel economy. Try playing with the built-in display and it should get you the basics of what you're looking for. If it's still too low-end, then some of the obd II-based listing the others suggested may work.
