I have two items on my wish list:
1. Variable speed, constant pressure, "silent" pump (instead of an accumulator) like this one:
http://www.campingworld.com/browse/s...m?skunum=21398 That noisy pump is my biggest irritant with my TM, but replacing it with one of these quiet models may be a royal PITA...the quiet ones are substantially longer and there's not much room under the sink in my 2720SL for plumbing revisions.
2. An electronic thermostat with programmable setbacks to replace the mechanical jobbie that TM installs. Since I camp in places where the night time temps drop into the low 40s/high 30s (even in summer)...and I let my TM interior temp drop down to around 50 at night (to save propane and battery), my first action in the morning is to hop out of the sack to up the thermostat...then I hop right back into the sack until the furnace can bring the temp up to around 60. 'Twould be darn nice to have a thermostat that's smart enough to do that for me.
One enhacement that I already did (beyond the solar panels) is installation of an electric tongue jack. My hand cranked one would occaisionally jump a thread...and I was getting tired of breaking into a sweat on a hot day from cranking the tongue up and down to hook up the TM. Camping World had/has a great price on these 3000 lb jacks (

). Pretty easy to install too...it bolted right in and all I had to do was put a 30 amp circuit breaker in the battery compartment and run a 10 guage wire up to the front of the trailer. As this jack has a 3000 lb capacity, after I get the TM coupler latched on my TV's ball, I use the jack to raise both TM & TV up to level so that hooking up the WDH's bars is almost effortless.
