Receiver access card question

Thanks to all who responded so quickly! I recently added a receiver to my DirecTv account for my RV that I purchased through DirecTv. It is showing on my DTV equipment account page as H24-100. I paid $100 to DTV for it and paying $6.99/mth for the service. I was not given the option to buy a DVR receiver (I believe it is model H24-200). On eBay I see H24-200 DVR receivers for under $50; hence my question to the forum. So if the access card is paired to the receiver Serial Number, is there a way to get a DVR receiver to replace my current receiver? Can I switch it though DTV and pay the extra cost for the upgraded receiver? If, so will the monthly service fee go up from $6.99/mth? Thx for all your help everyone!

Sorry, I meant H24-100 & H24-200 (DVR).

HR24-200 DVR

My current RV receiver, showing on my online DTV acct page is:

H24-100

I purchased/leased it (whatever the terms-I paid $100 to DTV) approx 4-6 mths ago. I then purchased a Slim Line 3 SWM Dish from Solid Signal and got everything working perfectly. I just wish I had a DVR receiver instead now but as I stated, the DTV rep never offered me a DVR receiver option. Can I switch out my current non-DVR receiver for a DVR receiver though DTV? Or what other options do I have if any? Thx 

Thanks so much for all your help and suggestions.

Lastly

FYI- I spent HOURS and HOURS talking to DTV knuckleheads in Manila (no offense to the Philippines) about adding a receiver to my account for my RV! It was literally torture and then trying to activate it was beyond torture! I will DEFINITELY take your "cancel" advise in the future. Thx very much for that!!!

I've had a DTV account with 3 Genie boxes (now 4 boxes) including a DVR for probably 7-10 years.

I see the HR24 receiver on Solid Signal for $199. So I buy/lease it, then pay DTV another $119 activation fee (just looked it up)- and I'm stuck with my current H24 box that I can't sell or return for a credit! Do I still need to pay the $7/mth for it for the remainder of the 24 month agreement even if I don't use it and replace it for a DVR receiver? So it looks like to switch to a DVR for my RV, I would be out of pocket approx $450 plus if I need to pay the $7/mth fee for 18 additional months- another $126 for a total of around $575?!?! WOW- not sure if that makes sense for as little time we use the RV. Is this correct?

Excellent info and advise! Thank you again for all your help!

Ya, DTV charged me a $99 Service Call/Dispatch Fee for the local service tech to bring me the H24 receiver for my RV- and I told the rep on the phone my RV was in storage an hour and a half away and I would be installing/setting it up myself at a later date- I asked to please mail me the box or let me pick it up at an DTV office location. NO GO- they said tech HAD to deliver it and charge me $99 PLUS the $19.95 Activation Fee- $119 total. I was so worn out trying to get an RV box I didn't argue- I just wanted service in my RV (and they were hinting they don't usually do receivers for RV any longer)! I definitely went over 24 mths, in good standing, without doing any upgrades prior to the RV box.

So basically, to change my receiver to add DVR capability, it would be $199 to lease it from Solid Signal plus the $119 I already spent- so about $320 ($199 more). OK, I'll think about it and decide.

Thx again-  Have a great evening, Rick
