Check with Dinosaur Electronics. They make custom boards for many furnace applications. If you know the factory part number, they have an interchange data base. If not, you can search by manufacturers model number. I have an unused Dinosaur UIB-L board kicking around the shop somewhere. If it’s a match it’s yours for postage.

Toyota 20R engines are famous for cracked exhaust manifold ( usually between #2 and #3 exhaust ports). I realize yours is a 22R, but the same issues occurred with that block too. Turns out the heat shield is the culprit. The excess heat generated by the hot exhaust gets trapped underneath the shield. With no way to dissipate, it ends up cracking the cast iron header. Unless you feel you absolutely need that heat shield, I’d delete it completely. Not to be a doomsayer, but the cracked manifold is often mistaken for a leaky exhaust gasket.

Check your connections on the battery post(s). Also, clean the negative cable connection where it grounds to the frame. A bad ground on the coach battery will cause the same symptoms.

What make and model # of furnace ? Is your coach battery fully charged ? Did you inspect the outside exhaust/intake port for blockage such as wasp nests ? Are there any individual shutoff valves for the furnace that may be closed ? Is the LP tank full ? If all the above checkout ok, chances are it’s a bad circuit board. These can be replaced. A good go to company is Dinosaur Electrical.

Why do you need to replace the valve?

Try “propane warehouse “. Many propane parts and accessories. Prices are very reasonable.

You can try to find the exact model # for replacement. I purchased a 2 stage propane regulator for grill application at Lowe’s for about $45. Fit my system with no modifications. Think it was a “chargrill “. Online try propane warehouse. Lots of propane accessories at really reasonable prices.

Your regulator is left hand thread. This means you turn it the opposite of what you would normally do. Clockwise will loosen, counterclockwise will tighten. You may have to tap the wrench with a rubber mallet as you probably over tightened it thinking it was right hand thread. Use a flare wrench if you have one. Less chance of rounding over the nut.

Could you apply some vinyl edging to your plexiglass to make a tighter fitment to the gasket? I’ve attached a link to give you an idea of my thought process. https://www.walmart.com/ip/Uxcell-Trim-Seal-PVC-U-Seal-Fits-0-5-1mm-Edge-3-28Ft-0-2-Height-Transparent/626892491?wmlspartner=wlpa&selectedSellerId=571&adid=22222222228626892491_571_14069003552_202077872&wl0=&wl1=g&wl2=m&wl3=42423897272&wl4=aud-393207457166:pla-295289030566&wl5=9009733&wl6=&wl7=&wl8=&wl9=pla&wl10=111838760&wl11=online&wl12=626892491_571&veh=sem&gad_source=1&gbraid=0AAAAADmfBIp9GUXZaaLs8ugzJ-rbPmyGu&gclid=EAIaIQobChMI7aOU1879hAMVGxatBh3A1g58EAQYBSABEgKclvD_BwE

If you’re buying something like a memory foam topper they can be cut down to fit. I did that with mine once. Get the closest size larger than the mattress then cut to fit.

Welcome to our forum. The 6 lug axle is very good. Aside from normal due diligence, my first concern is why the roof is covered with plywood. I’m guessing it’s for snow abatement. It could also be due to potential roof leak issues. New England uses a fair amount of road salt during the winter months. I would check the frame over very carefully for any rot. Surface rust is not a big deal. Tires should be recent. Check the date codes on each tire. Google will tell you how to do that. Others will also chip in with advice. This is the premiere site for Toyota motorhomes.

I second Thunderer. On my second set now. Easily get 40K out of them.

There’s a forum for Toyota mini trucks I belong to. A member there is building a flatbed using the 6 lug ff axle. According to his build thread he’s sourced most all the parts for the rebuild from box stores. I was unable to copy the link, so did a screenshot of his axle. The site is toyotaminis. com. I’ve been a member for over 10 years. Very knowledgeable people for Toyota mechanical’s. He would be a good resource for your axle
